MCC (Microsoft Connected Cache for ISP)
by Aaron Gould 16 Nov '23

16 Nov '23

Is MCC for ISP comparable to other well-known CDN's, like Facebook FNA, Netflix OCA, etc? Anyone have any experience with MCC in an ISP environment, and do you see much bandwidth savings with it? https://learn.microsoft.com/en-us/windows/deployment/do/mcc-isp -- -Aaron

DDOS scrubbing
by john doe 15 Nov '23

15 Nov '23

Hi! I could not find any recent thread on the list about ddos scrubbing devices. We are looking into some kind of hybrid service with onprem hardware and scrubbing centers. At the moment we are evaluating NSFocus and Riorey, do the list have any experience from them? Johan

Zayo woes
by JASON BOTHE 14 Nov '23

14 Nov '23

Does anyone know what’s happening at Zayo? Tickets are taking weeks and months to get resolved, much less get a tech assigned to them. The folks answering the noc phone are mere order takers and are only reading from a script, manager on duty/escalation lines go to voicemail. If anyone can help get to a human in the transport group, that would be great. I’ve given up all hope at this point. Appreciated. Jason

Strange IPSEC traffic
by Shawn L 14 Nov '23

14 Nov '23

Is anyone else seeing a lot of 'strange' IPSEC traffic? We started seeing logs of IPSEC with invalid spi on Friday. We're seeing it on pretty much all of our PE routers, none of which are setup to do anything VPN related. Most are just routing local customer traffic. decaps: rec'd IPSEC packet has invalid spi for destaddr=X.X.X.X, prot=50, spi=0x9D2D0000(2636972032), srcaddr=211.112.195.167, input interface=TenGigabitEthernet0/0/11 decaps: rec'd IPSEC packet has invalid spi for destaddr=Y.Y.Y.Y, prot=50, spi=0x14690000(342425600), srcaddr=74.116.56.244, input interface=TenGigabitEthernet0/0/5 The destination address is always one of our customer's ip addresses. The source seems to be all over the place, mostly Russia, Korea, China or south east asia. It's not really impacting anything at the moment, just rather annoying. Thanks Shawn

Celebration: RADB appears to now filter RPKI-invalid IRR route/route6 objects
by Job Snijders 14 Nov '23

14 Nov '23

Dear NANOG, It appears the WHOIS service at whois.radb.net is now filtering out RPKI-invalid IRR route/route6 objects for common expansion queries! This really is exciting and excellent news. I'll elaborate a bit on what this exactly means. Example ROA & IRR object ======================== Take for example the 194.32.71.0/24 test prefix: https://irrexplorer.nlnog.net/prefix/194.32.71.0/24 For experimental purposes, NTT (ages ago) created a cryptographically verifiable RPKI ROA to indicate that any BGP announcements for 194.32.71.0/24 or-longer are RPKI-invalid: https://console.rpki-client.org/rpki.ripe.net/repository/DEFAULT/01/ee8b98-… RPKI ROA: +--------------------------------+ | Prefix: 194.32.71.0/24 | | Origin: AS 0 | | Trust Anchor: RIPE NCC | +--------------------------------+ Additionally, an IRR route object was created in the RIPE NCC managed 'RIPE' IRR database: https://apps.db.ripe.net/db-web-ui/query?bflag=false&dflag=false&rflag=true… IRR Route Object: +--------------------------------+ | route: 194.32.71.0/24 | | origin: AS15562 | | pingable: 194.32.71.1 | | ... | | source: RIPE | +--------------------------------+ Obviously, the above IRR route object is in conflict with the sole RPKI ROA for 194.32.71.0/24, which designated AS 0 exclusively. Following the reasoning that IRR route objects describe possible BGP states, and in BGP the combo 194.32.71.0/24AS15562 would be rejected; it makes sense to go a step further and filter out IRR objects which are RPKI-invalid too. This concept of filtering out RPKI-invalid IRR objects was described in https://www.ripe.net/publications/docs/ripe-731 and also implemented in IRRd v4. RPKI-Invalids no longer visible via whois.radb.net ================================================== Since recently, whois.radb.net indeed applies such filtering and no longer displays the RPKI-conflicting IRR object for 194.32.71.0/24: $ whois -h whois.radb.net 194.32.71.0/24 % No entries found for the selected source(s). The above 'No entries found' output means that the IRRd instance filtered out the RPKI-invalid IRR objects! This is great :-) In doing so, RADB actively helps safeguard the interests of resource holders: it no longer is possible for adversaries to create IRR route objects which are in conflict with RPKI ROAs via the RADB service, and RADB also filters out RPKI-invalid IRR route/route6 objects received via the NRTM mirror streams; additionally, this filter mechanism helps clean up historical route objects that have become irrelevant due to transfers. The RPKI-based filtering mechanism cleans up the past and helps protect going forward. Of course RADB isn't the only IRR operator who apply RPKI-based filtering, NTT is another one, as is TC, etc; but this week's RADB migration it certainly moves the needle in a significant way: now all the world's largest IRR mirrors apply RPKI-based filtering! :-) Thanks ====== I'd like to express appreciation to the NTT crew (past and present) for helping launch the IRRd v4 initiative: Dorian Kim, Shawn Morris, Michael Wheeler, Dan Lowe, Troy Boudreau, Camilo Cardona; to Sasha Romijn from Reliably Coded for leading the development of IRRd v4; and to the Merit crew who diligently worked to migrate RADB away from legacy IRRd - I believe we collectively benefit from their efforts. The IRRd cross-organizational open-source project is here: http://irrd.net/ お疲れ様です! Kind regards, Job

Am I the only one who thinks this is disconcerting?
by Owen DeLong 13 Nov '23

13 Nov '23

https://dnsviz.net/d/10.159.192.in-addr.arpa/dnssec/ Seems to report a bunch of errors in the DS records for 192.in-addr.arpa held in the in-addr.arpa zone. I figured I’d wait a few days and try again the first few times I encountered this, but it’s persisted for more than two weeks now. Owen

Appropriate venue to find out about the state of art of spear phishing defense?
by Michael Thomas 13 Nov '23

13 Nov '23

I know this is only tangentially relevant to nanog, but I'm curious if anybody knows where I can ask what orgs do to combat spear phishing? Spear phishing doesn't require that you deploy DMARC since you can know your own policy even if you aren't comfortable publishing it to the world. tia, Mike
