Yahoo Postmaster

If there is a YAHOO! Postmaster contact available, can you please contact me off list? I need to investigate a customer's "TS03" listing of a very large netblock (/16) and I'm afraid regular Yahoo! forms are leading me nowhere but frustration and no results. Thanks.

Contact at GoGo Internet?
by Matt Simmons 24 Jun '13

24 Jun '13

For a reason that I'm unable to ascertain, GoGo In-Flight Internet can route to my university's network blog, but not to my specific college's. Does anyone have a contact there that I could reach out to and work to figure this out with? Thanks! --Matt Simmons -- LITTLE GIRL: But which cookie will you eat FIRST?

Multihop eBGP peering or VPN based eBGP peering
by Michael McConnell 24 Jun '13

24 Jun '13

Hello all, Any idea why more companies don't offer eBGP peering / multi hop peering? Its very common for providers to offer single or double hop peering, so why not 5 or 10 hops? In many cases people find it logical to perform single or double hop peering, why is peering any greater always frowned upon. I understand the logic that you can't control the path beyond a point, however I still see numerous advantages. One obvious advantages one is, imagine you east coast data centre and you had a eBGP peering session with a west coast router, you'd be able to control ingress via the west coast. (aka routing around an region outage that is effecting ingress) For example during the last hurricane around New Jersey, numerous tier 1's were down towards the atlantic and every peer for the atlantic was effected. One could have just made the ingress via the west coast the logical route. Thoughts?

Network diagnostics for the end user
by Jeffrey Ollie 24 Jun '13

24 Jun '13

Are there any tools out there that we could give to our end users to help diagnose network problems? We get a lot of "the Internet is slow" support calls and it would be helpful if we had something that would run on the end user's computer and help characterize the problem. We have central monitoring system of course but that doesn't always give a complete picture, as the problem could always be on the end user's computer - slow hard drive, not enough memory, wrong name servers, etc.

Re: /25's prefixes announced into global routing table?
by Andra Lutu 24 Jun '13

24 Jun '13

Hi, From public routing data we can see a total of 2,419 /25s prefixes announced from at least one of the monitors active in RIPE RIS and RouteViews. None of the /25s are actually advertised by all these monitors i.e. the /25s reach some but not all the ASes which take part in these projects. The actual distribution of how many unique routing tables sampled contain the /25s is the following: http://visibility.it.uc3m.es/len25_distro.html (out of the approx. 140 collectors that have a "full" routing table). The top 5 ASes that are originating the most /25s are: AS 11427: 462 /25s AS 4766: 273 /25s AS 45400: 109 /25s AS 14065: 82 /25s AS 3549: 57 /25s If you are interested in limited visibility prefixes, i.e., prefixes that are distributed to some but not all the "full" routing tables at the interdomain level, you can find more at http://visibility.it.uc3m.es/ and https://labs.ripe.net/Members/andra_lutu/the-bgp-visibility-scanner Best regards, Andra On 06/22/2013 12:00 AM, nanog-request(a)nanog.org wrote: > Date: Fri, 21 Jun 2013 13:56:02 -0600 > From: Michael McConnell<michael(a)winkstreaming.com> > To: North American Network Operators Group<nanog(a)nanog.org> > Subject: /25's prefixes announced into global routing table? > > Hello all, > > As the IPv4 space get smaller and smaller, does anyone think we'll see a time when /25's will be accepted for global BGP prefix announcement.

.biz DNSSEC borked
by Andre Tomt 24 Jun '13

24 Jun '13

Seems the entire .biz tld is failing DNSSEC validation now. All of my DNSSEC validating resolvers are tossing all domains in .biz. The non-signed domains too of course because trust of the tld itself cannot be established. http://dnssec-debugger.verisignlabs.com/nic.biz
