2 Developments in DNS Privacy

The presentation will give an update about some of the most recent developments in DNS privacy technologies including the latest encryption and discovery protocols, touching on related developments including Private Relay and Encrypted Client Hello. The focus will be on highlighting aspects of these developments of particular relevance for network operators to consider.

3 IPv4 Back to the Future: “Where we’re going, we don’t need IPv4!”

Service providers are building out networks to extend coverage to underserved communities and provide faster, more secure, and innovative services. One critical area that can be overlooked in the long list of network requirements is the need to provide IPv4-IPv6 connectivity. The price of scarce IPv4 addresses keeps rising and can become a surprising and unexpected cost for many operators. IPv6 is often not a viable near-term option as adoption is still uneven with many websites, subscriber devices, and servers currently supporting IPv4 only.

4 SentryPeer - A distributed peer to peer list of bad IP addresses and phone numbers collected via a SIP Honeypot

SentryPeer is a fraud detection tool. It lets bad actors try to make phone calls and saves the IP address they came from and number they tried to call. Those details are then used to block them at the service providers network and the next time a user/customer tries to call a collected number, it's blocked.

Traditionally this data is shipped to a central place, so you don't own the data you've collected. This project is all about Peer to Peer sharing of that data. The user owning the data and various Service Provider / Network Provider related feeds of the data is the key bit for me. I'm sick of all the services out there that keep it and sell it. If you've collected it, you should have the choice to keep it and/or opt in to share it with other SentryPeer community members via p2p methods.

The sharing part...you only get other users' data if you share yours. That's the key. It could be used (the sharing of data logic/feature) in many projects too if I get it right :-)

5 BNG Blaster - Open Source Network Tester

When we started to build and test our BNG software for open hardware platforms, we got increasingly frustrated with the abilities and test methodology of commercial network testing software. Most solutions come with a dedicated hardware chassis or VMs with high CPU and memory requirements. Commercial network testing software is often limited by strict licensing. When performing regression testing overnight on cloud servers we have a peak license use of hundreds of instances, which we do not need most of the day. Our reliability testing crew complains often about slow reconfiguration from one test scenario to the next. Reprogramming the network tester often takes an order of minutes before the test suite can be run but we want to start/stop a test within an order of seconds.

Therefore we decided to build an open source network test software initially focused on BNG and IPTV testing but constantly enhanced and planned for more common network equipment test cases.

The BNG Blaster is completely built from scratch targeted for max scaling with a small resource footprint, simple to use and easy to integrate in our test automation infrastructure. It is able to simulate more than hundred thousand PPPoE and IPoE subscribers including IPTV, L2TPv2, QoS, forwarding verification and convergence testing capabilities.

• High Scaling: > 100K sessions
• Low CPU and Memory Footprint: < 100MB memory for 16K sessions
• Portable: runs on every modern linux, virtual machines and containers
• User Space: all protocols are implemented in user-space from scratch and optimized for high performance
• IPTV: IGMP version 1, 2 and 3 with automated channel zapping test
• QoS: define and analyze traffic streams
• Automation: the BNG Blaster Controller provides an automation friendly REST API and robot keywords

At RtBrick we already migrated all our testing to BNG Blaster which saved us more money on commercial network testers than spent on development for this software. We also received great feedback from GitHub users around the world using it. Therefore we will continue to sponsor this project with the target to form a large community of users and contributors.

6 Survey of Reverse DNS in the UK

I have created a tool to do country-specific surveys of the state of reverse DNS deployment in the IPv4 space. I have a 5-minute lightning talk that reports the results of the survey for the UK (I'll run the numbers a day or two before UKNOF49) and then I gently remind the audience the importance of tagging publicly accessible network infrastructure elements with PTR records to help both their staff and the rest of the neteng world doing network troubleshooting.

7 The Road to 400G

LINX recently introduced the option of 400GE ports for members in partnership with its vendor partner, Nokia. This presentation covers why this is important, the complexity of a mixed vendor network and the development process to get to where we are today.

LINX’s most significant exchange is the LON1 LAN in London which has been converted from MPLS/VPLS to MPLS/EVPN. LINX now have a proven approach with a large scale EVPN network with multi-vendor approach to get to 400GE.

During this project LINX learnt that working with a mixed vendor solution brings significant challenges in testing, acceptance and in-house ownership. It also highlights problems with how standardised protocol implementation still varies.

Other IXPs, network designers and datacentre fabric operators will be interested in how LINX completed their journey, and what potential issues they should look out for themselves in their own progress towards 400GE.

8 Governing the "Ungovernable": One Giant Leap for the Root Server System in 2021

The world’s trust in DNS rests in no small part on the Root Server System (RSS). For three decades the RSS has operated 24 x 365 without interruption thanks to the services of a small group of organisationally diverse, fiercely independent, utterly dedicated, and highly collaborative Root Server Operators (RSO). The year 2021 began with a potential regulatory threat to the stability of the RSS and ended with a significant leap forward in developing its new governance model.

In this talk, we will review the threat to RSS stability from the European Union’s proposed NIS2 Directive and how this has been avoided (for now). After briefly considering how the RSS is governed today, we will discuss how RSSAC058 and ‘059 (published November 2021) represent a significant breakthrough in developing a new governance structure that seeks to assure the continued stability of the RSS and the Internet itself.

9 UKNOF Volunteer Recognition

UKNOF relies on volunteers to survive. In this session we will recognise the volunteers who make it a success. We will present plaques recognising the efforts by volunteers who have left the UKIF board and various committees. We will also welcome new volunteers who have joined the UKIF board, the Communications Committee, and taken leadership roles in the Programme Committee.
