For the first time we have had to deal with Sprint's routing policy as
defined by http://www.sprint.net/filter.htm. Here is the situation.
One of our dialup customers wants to access his website in the
206.116.31.0/24 network at another provider. PSI is advertising it as a
/24. According to Sprint's routing policy, they do not honour anything
longer than a /19 in 206.0.0.0/8 .
I am now in the position trying to explain to the very non-technical
customer, why he cant reach that site, which from his point of view just
seems like I am passing the buck...
Anyways, my question is, are their any other ISPs/NSPs that follow the same
guidelines. UUNet seems to honor it just fine, as does MCI. Is Sprint
more hardnosed than most ?

That is the wrong question to ask. The real question is who has been
handing out 206.116/16 like they were dealing cards? A quick look
at the announcments and in whois.arin.net reveals a bunch of /24
spread out over Canada.
Historically, and currently, the Canadians crowd the top of
the Tony Bates cidr list. Why is that?

P.S. I see iSTAR has 206.116/16.... why don't they announce it?
The owner of the block should be announcing the /16 It should not
be chopped up into a whole slew of /24's. It's not sprints fault. I would
contact iSTAR. If their customers are multihomed out of that space,
and (ex:) came to us, we would accept and announce that space, but not
everyone would accept it (such as sprint, and others).
If the person in that /24 is not connected to iSTAR, they should
have given the address space back already.
More folks should probally be filtering this:

That is the wrong question to ask. The real question is who has been
handing out 206.116/16 like they were dealing cards? A quick look
at the announcments and in whois.arin.net reveals a bunch of /24
spread out over Canada.
This is because historically, addresses in Canada were handed out without
regard to CIDR even after everyone else was doing CIDR allocations. A
couple of years ago the Canadian IP registry was shut down and allocations
since that time have followed CIDR guidelines more closely. If you want to
see an excellent example of the kind of things that used to happen, have a
look at "whois -h whois.arin.net 199.166.227". In 1994 I applied for a
CIDR block of two Class C's, i.e. a /23 and this is what I got. Look
closely now... If you still can't see the problem try writing both /24's
in binary one above the other.
Historically, and currently, the Canadians crowd the top of
the Tony Bates cidr list. Why is that?
Part of it is because of the above allocation problem but another large
part of the problem is a severe lack of clue. Not enough Canadians go to
NANOG meetings to learn how to run a network properly, especially at the
Canadian backbone providers. Even when there were 10 provincial backbones
within the CA*NET consortium, the knowledge transfer just did not take
place. In some provinces like Ontario the network operators seemed more
interested in socialist politics than in running a network properly.
Things are a bit better now in some regions and in some companies but
there is still a lot more knowledge sharing that could be done.
And if anyone wants to flame me for this, please don't inflict it on the
NANOG list. Instead, come see me in person this weekend at the 12th annual
Canadian Internet conference http://www.net98.bc.ca and tell me what a
twit I am. I'll even buy you a beer.
