BOGONs should be updated every now and then ...
by Fredy Künzler
We recently received an email saying
In the past few month these blocks should have become routable:
I know that BOGON filtering could be automated, but we never found the time to get it done properly, and, as the available IPv4 space is running out, the Bogon Route Server Project will become obsolete anytime soon.
We recently received an email saying
Please remove 174.0.0.0/8 from your bogon filter...and indeed, as time flies by, we had an outdated BOGON filter list implemented. IANA keeps allocating /8 to RIRs and if network administrators don't pay attention, parts of the internet could silently become unreachable.
In the past few month these blocks should have become routable:
112.0.0.0/8Therefore it's probably wise to check if you see any more specifics of these prefixes (on Cisco / Foundry / Quagga type "sh ip bgp 113.0.0.0/8 longer").
113.0.0.0/8
114.0.0.0/8
115.0.0.0/8
173.0.0.0/8
174.0.0.0/8
186.0.0.0/8
187.0.0.0/8
I know that BOGON filtering could be automated, but we never found the time to get it done properly, and, as the available IPv4 space is running out, the Bogon Route Server Project will become obsolete anytime soon.

IPv6 now! (says OECD)
by Fredy Künzler
Even the OECD (Organisation for Economic Co-operation and Development) preaches now IPv6! ... and I guess when official institutions start to worry, it's serious. Functionaries usually don't tend to be fast movers.
I recently asked a fellow service provider about his IPv6 plans, and the answer was a bit ignorant: "noone is paying me to implement IPv6, therefore I don't have a project". Looking back to the early days of the Internet, a lot of research and test-implementations have been done withouth payment, and it became the foundation of a whole industry. Money should not be the focus when evaluating IPv6, at least for another year or so.
I gave a presentation at the recent SwiNOG #16 meeting about implementing IPv6 in a providers backbone. In fact, IPv6 is much easier than people generally think. If you are a network professional, everything you know about BGP, subnetting, OSPF etc. is still valid, at least more or less.
If you plan to deploy IPv6 anytime soon, click through the slides, they might be helpful (or download the IPv6 Now! presentation):

IPv6-only hour at RIPE #56
by Fredy Künzler
Notes about the IPv6-only hour over there at blogg.ch. Yes, it works (more or less).
P.S. Peter, sorry. You have to bother translate.google.com again.
