Hello! I tried to contact AS18881, because some of their IPv6 networks are not propagated to AS3320. I used the addresses in the whois, but got no reply and the issue persists. This affects 2804:1b1:c000::/35 and others. Can anybody give a hint how to contact them? -- kind regards Marco

Root Zone DNSSEC Operational Update
by Wessels, Duane 10 Jun '25

10 Jun '25

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA256 Verisign, in its role as the root zone ZSK operator, is transitioning to a new Hardware Security Module (HSM) product for the root zone's Zone Signing Key (ZSK). The current HSM vendor, Ultra Intelligence & Communications, has announced their KeyperPLUS will no longer be supported by them. Verisign will use an HSM product from Thales for the root zone ZSK going forward. On July 1, 2025 we will begin using the Thales HSM to sign the root zone on a daily basis. Although we anticipate this will be a seamless change for end users and anticipate no problems, prudence dictates that we need a backout plan, should it become necessary. As part of our backout plan, we will be post-publishing the previous quarter's ZSK for a longer than normal period of time. Normally, following a quarterly ZSK rollover, the previous key is post-published for a period of 10 days. As part of our HSM transition, we will instead post-publish the previous ZSK for a period of 80 days. This provides ample time to remediate any issues that may arise as part of this transition, and should it become necessary, to revert to using the old HSM to sign the root zone. -----BEGIN PGP SIGNATURE----- iQEzBAEBCAAdFiEEvEG6oyZuoN5HQhnubJmkaajAmI0FAmhGex8ACgkQbJmkaajA mI1MEQgAo5/CB0GHYJq+4EqPCecevajsAhjcr4NXxViKyU5K3E//DwR82LIC9p6T HWLY1C0tiFk2Sg/3FbxF2arnUVC9yPJHOI5y2O+AE/BJibSVCyEEse+CbQkVljEd peaHNkkqp96AGgJiZv1On+B63Nog4CBrGMRxD14J0IAZShGbFqDZLRo6VhTHCCf+ isea/+1LbAbe/r2lTbm72q3a5lt/br6yRl37MZAbsJh8PyOAQE54jcnMlypL3qlx VribLjYduQAyKfUgMfVOXOionoY8i+4u1Rce9GXC130jklW7KXsp4un0SCGT5ByV gQWK5Hz73A4039CiUtjm3WqoIILIcg== =kLWP -----END PGP SIGNATURE-----

Tayga users?
by Andrew 02 Jun '25

02 Jun '25

Is anyone deploying Tayga in any capacity (production, test networks, at home, with clatd, …)? I’ve decided to ‘adopt’ the open source project, given it’s ability to both be very standards compliant (at least to the standards as they were in 2011), and act in virtually any translation-related role (not restricted to just CLAT or just NAT64 or just SIIT) But I’m interested in hearing how you are using it, what friction you have in deploying it, etc. This is mostly motivated by my desire to stand up demonstration networks for a variety of transition tech options, and with how versatile Tayga is, it can act in essentially all of the major roles involving v4-v6 translation with different configuration and routing tables and without any complex namespace setup. I’m also an embedded programmer by trade, so dealing with low level C is very much my thing. https://github.com/apalrd/tayga/ [tayga.png] [apalrd/tayga: Tayga NAT64 Daemon](https://github.com/apalrd/tayga/) [github.com](https://github.com/apalrd/tayga/) is where I've put the repo. I started with the original tar.gz, merged in all of the patches from the Debian project, plus one patch from FreeBSD, and went from there. I'm mostly working on an RFC7915 test suite and fixing any bugs identified by the test suite, and after that I can make more changes / improvements without worrying about hidden breakage. Yes, I know Github does not support IPv6, but I felt like that collaborators are more likely to have Github accounts and know how to use it vs self hosting or other platforms). Andrew

RIPE Probe Behind IPS
by Mike Hammett 02 Jun '25

02 Jun '25

How are you handling blocking and notifications if you have a RIPE Atlas Probe behind an IPS? Most traffic is fine, but occasionally, someone will use my probe to ping some IP that's blocked. ----- Mike Hammett Intelligent Computing Solutions http://www.ics-il.com Midwest-IX http://www.midwest-ix.com
