Paging Bill Manning...

Unfortunately, we've tried to reach Bill, as well as other folks at
EP.NET to no avail, and this is impacting us quite negatively.

[snip]

Not available in any routing tables I have access to or any of the looking
glasses from http://www.nanog.org/lookingglass.html.

this is significant because any in-addr blocks that are authoritative @
flag.ep.net and dot.ep.net will now suffer from reverse name resolution
issues.

- From ATT route server:

route-server>sh ip bgp 198.32.4.13
% Network not in table

- From CerfNET route server:

route-server>sh ip bgp 198.32.4.13
% Network not in table

Allstream Toronto:

route-server.east>sh ip bgp 198.32.4.13
% Network not in table

This has been a problem since yesterday evening.

FYI, some of our address space has been sub-allocated via EP.net
and relies on it's reachability:

Congratulations, finally, after almost a year after the shutdown and
deprecation of the 6bone address space, returning it to IANA, all the
6bone prefixes are finally gone from the IPv6 routing tables at all
ISP's peering with GRH (which thus more or less gives a global IPv6 BGP
view)

Thanks Bill for finally(!) shutting down the machines that you where
still using for announcing these prefixes. This definitely shows that
everybody is done experimenting with IPv6, expect for the upcoming Great
IPv6 Experiment of course :wink:

For the folks still using only IPv4: Remember that Geoff Huston and Tony
Hain have now aligned their prognoses for IPv4 Address Depletion: 2009
is the new date, so if you are not doing IPv6 yet, you better start
doing something about it, or you will be too late, and everybody who did
do something about it, is going to point and laugh at you while
ridiculing you saying "we told you so", which is going to be quite a lot
of fun :slight_smile:

Greets,
Jeroen

(only partially kidding, but it was time that 6bone routes finally
disappeared, he can resurrect the rest of ep.net though)

Is it just me or is this happening again? Re-paging :wink:

Thanks

Since 198.32.0.0/16 is cut up and used by many, many different people in many disconnected networks, it seems to me that the absence of 198.32.0.0/16 in the RIB is a feature, not a bug.

(And I'm fairly sure this was pointed out last time, too :slight_smile:

However 198.32.2.10 and 198.32.4.13 (ep.net DNS) are not covered by any active prefix right now, 198.32/16 or otherwise, so that is a bug and not a feature :wink: I am not so concerned about 198.32/16 not showing up as I am that no other prefix which will handle those hosts is either.

Thanks
Chris

A failure to reach ep.net's nameservers is presumably something to be taken up with ep.net, though, not NANOG :slight_smile:

Looks like the failure was temporary:

Huh. flag.ep.net was renamed flag.ip4.int?

Given that the best I can find out about ip4.int is a very brief and long-expired I-D from 1996, why is this domain still in the root zone?

At least ip6.int. was actually used for a brief time...
