About 90 people met in Manchester at UKNOF49 on Tuesday, 12 April 2022. 21 people participated online and engaged with industry colleagues using our Mattermost server. This was another hybrid event. Most speakers presented in Manchester with some joining over the Internet. Seven speakers presented on a variety of Internet operations topics. We also programmed plenty of time for people to speak with each other.

We will publish recordings of the talks from UKNOF49, so you can review the details of talks you enjoyed or catch up on a talk you missed.


  • The opening talk came from Andrew Campling from 419 Consulting. He updated us on developments in DNS privacy technologies, including the latest encryption and discovery protocols.
  • Simon Jackson from A10 Networks then gave a sponsor presentation on providing Internet access to underserved communities despite the lack of IPv4 space, using CGNAT.
  • After the break, Gavin Henry of SureVoIP presented SentryPeer. It’s a peer-to-peer fraud detection tool that reduces spam calls by letting users share data.
  • Christian Giese from RtBrick then spoke about BNG Blaster. This is an open source network tester with a small resource footprint and a lot of capabilities.
  • After lunch, David Huberman from ICANN presented the results of a survey of IPv4 reverse DNS in the UK. He found that about two-thirds of IPv4 blocks allocated to UK networks are both in the DFZ and have a PTR. He also found that about a fifth are not in the DFZ.
  • Mariano Juliá from LINX then spoke about their new 400GE ports. He described how they have converted their LON1 from MPLS/VPLS to MPLS/EVPN.
  • Robert Carolina from ISC then spoke about Root Server System governance. He focused on the European Union’s proposed NIS2 Directive and how its threat to stability has been avoided – for now.

After the break we recognised the volunteers who have contributed to UKNOF over the years. We recognised 18 former members of the Programme Committee in a small ceremony. And we renewed the call for people to join the Programme Committee throughout the day. If you’re interested in joining, please contact chairs@uknof.org.uk.
