However, the\nincreasing centralization of DNS traffic through large content-delivery hyper-giants (such as Google), coupled with the fact that the majority of DNS communication traditionally runs over unencrypted transports (UDP/TCP), has led to increased security and privacy concerns. In this talk, I will\npresent recent results on the resiliency and efficiency of DNS, the state of adoption of protocols that enable DNS privacy and their performance implications. I will conclude with a future outlook of a protocol design whereby traditional communications no longer have to trade performance for privacy, but can achieve the best of both worlds: privacy-enhancing DNS + secure communication on the Web.\n\nLicensed to the public under http://creativecommons.org/licenses/by/4.0","original_language":"eng","persons":["Prof. Dr. Vaibhav Bajpai"],"tags":["55903","denog16","Auditorium","2024","Day 2"],"view_count":136,"promoted":false,"date":"2024-11-19T11:30:00.000+01:00","release_date":"2024-11-19T00:00:00.000+01:00","updated_at":"2026-03-03T11:00:07.532+01:00","length":1449,"duration":1449,"thumb_url":"https://static.media.ccc.de/media/events/denog/denog16/55903-2b86dee9-ae97-5996-a86e-0e7f7cc6bf33.jpg","poster_url":"https://static.media.ccc.de/media/events/denog/denog16/55903-2b86dee9-ae97-5996-a86e-0e7f7cc6bf33_preview.jpg","timeline_url":"https://static.media.ccc.de/media/events/denog/denog16/55903-2b86dee9-ae97-5996-a86e-0e7f7cc6bf33.timeline.jpg","thumbnails_url":"https://static.media.ccc.de/media/events/denog/denog16/55903-2b86dee9-ae97-5996-a86e-0e7f7cc6bf33.thumbnails.vtt","frontend_link":"https://media.ccc.de/v/denog16-55903-measuring-the-state-of-dns-privacy-past-present-and-future","url":"https://api.media.ccc.de/public/events/2b86dee9-ae97-5996-a86e-0e7f7cc6bf33","conference_title":"DENOG16","conference_url":"https://api.media.ccc.de/public/conferences/denog16","related":[]},{"guid":"682c9a42-0a18-5c00-b3a2-7aa5c46ad429","title":"VPP: A 1Tbps+ router with a single IPv4 address","subtitle":null,"slug":"denog16-53110-vpp-a-1tbps-router-with-a-single-ipv4-address","link":"https://pretalx.com/denog16/talk/YGU3SW/","description":"In this talk, we explore the changes needed to convert a set of fully open source amd64 based VPP routers running in AS8298 to be able to use exactly one IPv4 and IPv6 address in an OSPFv3 and iBGP configuration.

This includes the SCION Research \u0026 Education Network (SCIERA) which includes connections to OVGU Magdeburg. It is also currently being evaluated for use in government, power utility, aviation, military and other applications, with a number of vendors interested in implementing it in their products. \n\nThis talk will discuss the SCION design and architecture, its trust model, how it can be deployed, as well as some deployment experiences to-date.

However, this initial step is just the beginning of a complex journey toward achieving sustainability. One of the most significant challenges these companies face is addressing Scope 3 emissions, which are generated by their supply chains and lie outside their direct control.\r\n\r\nIn this presentation, I will discuss the current state of sustainability efforts within the telecom industry, with a particular focus on the intricacies of reducing Scope 3 emissions. Rather than offering quick fixes, I will explore practical approaches companies can consider, such as switching to more sustainable suppliers, collaborating closely with existing suppliers, and gradually introducing contractual clauses that emphasize sustainability.\r\n\r\nAttendees will gain a realistic understanding of the challenges involved and will be introduced to strategies that can help their organizations begin the process of reducing their supply chain's carbon footprint. This discussion aims to provide a balanced view, emphasizing that while these steps are crucial, they require time, commitment, and a willingness to engage in long-term efforts.\r\n\r\nLicensed to the public under http://creativecommons.org/licenses/by/4.0","original_language":"eng","persons":["Nicol Nógrádi"],"tags":["55438","denog16","Auditorium","2024","Day 1"],"view_count":28,"promoted":false,"date":"2024-11-18T11:30:00.000+01:00","release_date":"2024-11-19T00:00:00.000+01:00","updated_at":"2026-01-11T00:00:26.249+01:00","length":1486,"duration":1486,"thumb_url":"https://static.media.ccc.de/media/events/denog/denog16/55438-79e323b8-dca3-5ff5-a666-8e93ddba47d8.jpg","poster_url":"https://static.media.ccc.de/media/events/denog/denog16/55438-79e323b8-dca3-5ff5-a666-8e93ddba47d8_preview.jpg","timeline_url":"https://static.media.ccc.de/media/events/denog/denog16/55438-79e323b8-dca3-5ff5-a666-8e93ddba47d8.timeline.jpg","thumbnails_url":"https://static.media.ccc.de/media/events/denog/denog16/55438-79e323b8-dca3-5ff5-a666-8e93ddba47d8.thumbnails.vtt","frontend_link":"https://media.ccc.de/v/denog16-55438-creating-a-sustainable-supply-chain-in-the-network-industry","url":"https://api.media.ccc.de/public/events/79e323b8-dca3-5ff5-a666-8e93ddba47d8","conference_title":"DENOG16","conference_url":"https://api.media.ccc.de/public/conferences/denog16","related":[]},{"guid":"198282aa-1b01-56d6-8549-b1ca11983889","title":"IXP Update","subtitle":null,"slug":"denog16-54999-ixp-update","link":"https://pretalx.com/denog16/talk/Y9RMD9/","description":"News from IXPs in Germany\nAs introduced 2021 we collect some parameters from all IXPs, which are active in Germany. \nThis talk aggregates the Updates for all the IXPs in a common format and will be presented in a neutral way.\n\nLicensed to the public under http://creativecommons.org/licenses/by/4.0","original_language":"eng","persons":["Tim Kleefass"],"tags":["54999","denog16","Auditorium","2024","Day 2"],"view_count":101,"promoted":false,"date":"2024-11-19T15:00:00.000+01:00","release_date":"2024-11-19T00:00:00.000+01:00","updated_at":"2025-11-09T21:30:05.607+01:00","length":1757,"duration":1757,"thumb_url":"https://static.media.ccc.de/media/events/denog/denog16/54999-198282aa-1b01-56d6-8549-b1ca11983889.jpg","poster_url":"https://static.media.ccc.de/media/events/denog/denog16/54999-198282aa-1b01-56d6-8549-b1ca11983889_preview.jpg","timeline_url":"https://static.media.ccc.de/media/events/denog/denog16/54999-198282aa-1b01-56d6-8549-b1ca11983889.timeline.jpg","thumbnails_url":"https://static.media.ccc.de/media/events/denog/denog16/54999-198282aa-1b01-56d6-8549-b1ca11983889.thumbnails.vtt","frontend_link":"https://media.ccc.de/v/denog16-54999-ixp-update","url":"https://api.media.ccc.de/public/events/198282aa-1b01-56d6-8549-b1ca11983889","conference_title":"DENOG16","conference_url":"https://api.media.ccc.de/public/conferences/denog16","related":[]},{"guid":"f0945a87-aaaa-53b6-ac98-eaa3d5652d3b","title":"Carrier Scale DNS - DNS@DT","subtitle":null,"slug":"denog16-55504-carrier-scale-dns-dns-dt","link":"https://pretalx.com/denog16/talk/GJGBFQ/","description":"This talk will give an overview of DTs DNS platform and the challenges arising from carrier scale DNS deployments.

Additionally, we account for factors such as temperature and cable length to predict the duration for which a reliable network connection can be sustained between transceivers. The analysis, based on data retrieved using a Flexbox, focuses on comparing the reliability of coherent (16QAM) and non-coherent (PAM4) transceivers, with a detailed discussion on the implications of these technologies on network performance.

For our purposes, we require full-depth racks, access from both sides, and active cooling. So we could either go for smaller, hardened outdoor equipment, which limits the choice of devices. Or we’d have to buy concrete data center containers the size of a garage, which are larger than we need, take more bureaucracy to build, and are also expensive.\r\n\r\nTo bridge this gap and keep the costs reasonable, we designed our own micro-datacenter, basically a larger street cabinet tailored specifically to our requirements: It provides active cooling, front and rear access, and fits full-depth devices while providing redundant power and sufficient protection from the elements.\r\n\r\nThis adventure took us deep into the engineering world of the infrastructure required for operating network devices. Have you ever had to consider cooling capacities, battery temperatures, air-flow velocities, or noise emission laws? We take you through the design process as well as the lessons we learned on the construction site and the operational experiences after finally taking the network into production.\r\n\r\nLicensed to the public under http://creativecommons.org/licenses/by/4.0","original_language":"eng","persons":["Leon Weber","Julia Sontag"],"tags":["55071","denog16","Auditorium","2024","Day 1"],"view_count":164,"promoted":false,"date":"2024-11-18T10:30:00.000+01:00","release_date":"2024-11-18T00:00:00.000+01:00","updated_at":"2026-03-12T23:45:06.316+01:00","length":1644,"duration":1644,"thumb_url":"https://static.media.ccc.de/media/events/denog/denog16/55071-2fd3a1b5-545b-5b55-ae92-ca5b7b8d2799.jpg","poster_url":"https://static.media.ccc.de/media/events/denog/denog16/55071-2fd3a1b5-545b-5b55-ae92-ca5b7b8d2799_preview.jpg","timeline_url":"https://static.media.ccc.de/media/events/denog/denog16/55071-2fd3a1b5-545b-5b55-ae92-ca5b7b8d2799.timeline.jpg","thumbnails_url":"https://static.media.ccc.de/media/events/denog/denog16/55071-2fd3a1b5-545b-5b55-ae92-ca5b7b8d2799.thumbnails.vtt","frontend_link":"https://media.ccc.de/v/denog16-55071-the-elephant-on-an-adventure-a-custom-built-shelter-for-network-devices","url":"https://api.media.ccc.de/public/events/2fd3a1b5-545b-5b55-ae92-ca5b7b8d2799","conference_title":"DENOG16","conference_url":"https://api.media.ccc.de/public/conferences/denog16","related":[]},{"guid":"4281547b-c0f4-51b0-9f50-f82a6645e4d1","title":"Submarine cables - lifelines of countries and continents","subtitle":null,"slug":"denog16-54594-submarine-cables-lifelines-of-countries-and-continents","link":"https://pretalx.com/denog16/talk/CKRBRG/","description":"In recent years, we’ve heard a bit more about submarine cables, mostly related to fiber cuts.

Is it just about resiliency and shorter routes, or are there other differentiators?\n\nThis talk will provide insight into the construction, operation, maintenance, and selection of submarine cables, using the connections between the United Kingdom and Continental Europe as an example.\nWe will dive into what it takes to construct a submarine cable, discover why and how it breaks, and provide guidance on what to consider when purchasing.\n\nLicensed to the public under http://creativecommons.org/licenses/by/4.0","original_language":"eng","persons":["Moritz Frenzel"],"tags":["54594","denog16","Auditorium","2024","Day 1"],"view_count":328,"promoted":false,"date":"2024-11-18T14:30:00.000+01:00","release_date":"2024-11-19T00:00:00.000+01:00","updated_at":"2026-02-04T11:15:11.800+01:00","length":1294,"duration":1294,"thumb_url":"https://static.media.ccc.de/media/events/denog/denog16/54594-4281547b-c0f4-51b0-9f50-f82a6645e4d1.jpg","poster_url":"https://static.media.ccc.de/media/events/denog/denog16/54594-4281547b-c0f4-51b0-9f50-f82a6645e4d1_preview.jpg","timeline_url":"https://static.media.ccc.de/media/events/denog/denog16/54594-4281547b-c0f4-51b0-9f50-f82a6645e4d1.timeline.jpg","thumbnails_url":"https://static.media.ccc.de/media/events/denog/denog16/54594-4281547b-c0f4-51b0-9f50-f82a6645e4d1.thumbnails.vtt","frontend_link":"https://media.ccc.de/v/denog16-54594-submarine-cables-lifelines-of-countries-and-continents","url":"https://api.media.ccc.de/public/events/4281547b-c0f4-51b0-9f50-f82a6645e4d1","conference_title":"DENOG16","conference_url":"https://api.media.ccc.de/public/conferences/denog16","related":[]},{"guid":"d861dcd6-6e05-521c-bc00-4737170671fc","title":"From shared broadcast domain into fully routed network without renumbering","subtitle":null,"slug":"denog16-55432-from-shared-broadcast-domain-into-fully-routed-network-without-renumbering","link":"https://pretalx.com/denog16/talk/WNS7MA/","description":"We had to move a couple of hundred machines from a big Layer 2 broadcast domain into a fully routed network. We also increased the bandwidth available for each server by mounting a new NIC into each server, To avoid synchronisation with service owners, we did not renumber hosts. In addition, there is connectivity to the large Layer 2 domain that is still in place and still has a few thousand hosts in need of migration.\n\nIn this talk you will learn how we engineered this migration, minimised downtime and ensured the documentation of our network is always up to date.\n\nLicensed to the public under http://creativecommons.org/licenses/by/4.0","original_language":"eng","persons":["Christoph Petrausch"],"tags":["55432","denog16","Auditorium","2024","Day 2"],"view_count":144,"promoted":false,"date":"2024-11-19T12:00:00.000+01:00","release_date":"2024-11-19T00:00:00.000+01:00","updated_at":"2026-01-04T12:15:12.652+01:00","length":1609,"duration":1609,"thumb_url":"https://static.media.ccc.de/media/events/denog/denog16/55432-d861dcd6-6e05-521c-bc00-4737170671fc.jpg","poster_url":"https://static.media.ccc.de/media/events/denog/denog16/55432-d861dcd6-6e05-521c-bc00-4737170671fc_preview.jpg","timeline_url":"https://static.media.ccc.de/media/events/denog/denog16/55432-d861dcd6-6e05-521c-bc00-4737170671fc.timeline.jpg","thumbnails_url":"https://static.media.ccc.de/media/events/denog/denog16/55432-d861dcd6-6e05-521c-bc00-4737170671fc.thumbnails.vtt","frontend_link":"https://media.ccc.de/v/denog16-55432-from-shared-broadcast-domain-into-fully-routed-network-without-renumbering","url":"https://api.media.ccc.de/public/events/d861dcd6-6e05-521c-bc00-4737170671fc","conference_title":"DENOG16","conference_url":"https://api.media.ccc.de/public/conferences/denog16","related":[]}]}
