Is there any particular reason why bluewin.ch does not support DMARC in the year 2023? Thanks, Juerg

Re: DNSSEC auto-disabled by SWITCH on some .ch domains?

G'day Franco, To the partners at least, in October 2022 informing them that anything containing digest-type 1 and/or key algorithm 5 oder 7 are no longer supported and will be deleted. This was done last week and digest-type 2 and key algorithm should be used. Since end of January 2023 you could not use them anymore. cheers Marcus Monday, May 1, 2023, 12:55:56 AM, you wrote: >> Hey SWINOGgers, >> I noticed that DNSSEC was somehow auto-disabled at registry level for some .ch domains I am responsible for. >> For these domains, no DS records are published anymore in the .ch zone, dnsviz shows a broken chain of trust. >> However, registrar data still shows that DNSSEC is enabled, but the registry (SWITCH) says it is not... >> Is this a known problem? >> Seems not all DNSSEC protected .ch domains are affected, which leads me to the suspicion that it might have >> to do with the algorithm being used. >> Did SWITCH turn off older algorithms, e.g. algo 7 (RSASHA1-NSEC3-SHA1)?

DNSSEC auto-disabled by SWITCH on some .ch domains?
by Franco Hug 01 May '23

01 May '23

Hey SWINOGgers, I noticed that DNSSEC was somehow auto-disabled at registry level for some .ch domains I am responsible for. For these domains, no DS records are published anymore in the .ch zone, dnsviz shows a broken chain of trust. However, registrar data still shows that DNSSEC is enabled, but the registry (SWITCH) says it is not... Is this a known problem? Seems not all DNSSEC protected .ch domains are affected, which leads me to the suspicion that it might have to do with the algorithm being used. Did SWITCH turn off older algorithms, e.g. algo 7 (RSASHA1-NSEC3-SHA1)? Did I miss an announcement?

Re: Datacenter switches
by Philipp Tobler 27 Apr '23

Hi Matthias, at the University of Bern, we are replacing our current Enterasys/Extreme/Brocade/Ruckus gear by Extreme Network models. For core/distribution/ToR, we opted for the 7400 and 5520 series with VOSS (Fabric engine) and so far, we are quite happy with the choice. The 5520-24x could fit your requirements - 10G copper is feasible with copper plugins. (max. 50% of copper plugins supported due to heat discipation) BTW, we use a mix of „original“ and Fexoptix plugins. Hope this helps - otherwise feel free to give me a call.

Datacenter switches
by Matthias Hertzog 27 Apr '23

27 Apr '23

Dear colleagues As some of you already figured, i‘m about to dive into the ISP scene again. „What a surprise“ ;-) I‘m currently evaluating datacenter switches. Current need is at least 12 10gig SFP ports and some 10gig copper ports. What brands and models are you guys using these days? I‘ve used cisco and Foundry/Brocade in the past, but i‘m open for recommendations. Thanks & have a nice day, Matthias

Looking for a /24. (or /23 or /22)
by Matthias Hertzog 23 Apr '23

23 Apr '23

Hi there! I’m looking for a /24 to buy. I have my own LIR and know how the transfer works. If you have something for sale, please let me know before i dive into the RIPE listing service and grow more grey hair due to non-responding people in there. Immediate and hassle-free payment guaranteed. Thanks & best wishes, Matthias
