Invalid ROA on Sunrise managed IP range
by Mike Kellenberger 12 Nov '18

12 Nov '18

Hi Could someone from Sunrise contact me off-list? We received a message about an invalid ROA of one of our customers IP-ranges, which is managed by Sunrise. I've tried contacting ip-reg(a)sunrise.net multiple times already, but I'm not getting any response.

.CH/.LI DNSSEC Algorithm Rollover
by Daniel Stirnimann 12 Nov '18

12 Nov '18

Hello, for your information, SWITCH will perform a DNSSEC algorithm rollover from RSA to ECDSA for ch. and li. ECDSA uses smaller keys and signatures than their RSA counterparts, which means responses to DNS queries are smaller. ECDSA was already standardised for use in DNSSEC in 2012. While switch.ch has been signed with ECDSA since 2016, IANA the root zone operator has only recently allowed TLDs to use it. The changes to the ch. and li. zones DNSKEY record are as following with times reported in UTC: 2018-11-21T13:30 Add new ECDSA key to DNSKEY record set 2018-12-21T13:30 Remove old RSA key from DNSKEY record set Between this interval, the chain of trust for ch. and li. will be updated in the root zone to point to the new ECDSA key only. Operators of DNSSEC validating DNS resolvers do not need to do anything. In the unlikely case that your validating DNS resolver only understands RSA but not ECDSA, then it will answer to ch. or li. queries as if they were not DNSSEC signed. You can test which DNSSEC algorithms are supported by the DNS resolver(s) configured on your system by visiting: https://rootcanary.org/test.html Best regards, Daniel Stirnimann, SWITCH -- SWITCH Daniel Stirnimann, SWITCH-CERT Werdstrasse 2, P.O.

Google DNS on Salt Mobile
by Gregor Riepl 01 Nov '18

01 Nov '18

Hi, It seems like Salt is no longer supplying their own DNS servers when establishing an LTE connection. Instead, the network responds with Google DNS servers (8.8.8.8 8.8.4.4). Is there a particular reason for that? I'd rather not send all my DNS requests to Google. Perhaps it's time to switch to private resolvers everywhere, if not even ISPs are providing that service any more... Thanks for any info. Greg

Announcing mirror.init7.net
by Fredy Kuenzler 30 Oct '18

30 Oct '18

As SWITCH has announced the sunset of http://mirror.switch.ch/ a while ago we are happy to announce a successor mirror.init7.net. https://mirror.init7.net By supporting IPv6 and legacy IPv4 and https as well as legacy http we hope to be able to support the Opensource- and Internet-Community in the future. In case your DNS resolver is broken we gave mirror.init7.net nice and easy to memorize IP addresses: https://2001:1620::1620 https://109.202.202.202 We would like to express our gratitude to SWITCH for providing a mirror service for much longer than a decade. PS. a hint for Debian and Ubuntu users - please ensure you have the package apt-transport-https installed to use https. -- Fredy Kuenzler Init7 (Switzerland) Ltd.

BGP LLGR, followup
by Vincent Bernat 22 Oct '18

22 Oct '18

Hey! A quick followup for my lightning talk from last year about BGP LLGR: - Support has been added in BIRD 1.6, BIRD 2 and GoBGP. AFAIK, Cisco still only supports it on VPN and FlowSpec families. - Draft 4 has been published and IANA has assigned capability code and well-known comunity (compatible with existing implementations). https://tools.ietf.org/html/draft-uttaro-idr-bgp-persistence-04 https://vincent.bernat.ch/en/blog/2018-bgp-llgr -- Make sure all variables are initialised before use. - The Elements of Programming Style (Kernighan & Plauger)
