Hi,
I am trying to figure out if either sprint (as1239) has blackholed a
single IP address in my network or something strange is up. If anyone has
transit connectivity to AS1239, can you tell me if Sprint is sending
199.212.134.9/32 as a prefix ??
e.g. from as1239's website looking glass
http://oxide.sprintlink.net/cgi-bin/glass.pl (only a traceroute interface)
sl-bb20-ana>trace 199.212.134.9
Type escape sequence to abort.
Tracing the route to smtp2.sentex.ca (199.212.134.9)
1 * * *
Yet, on that same subnet all else is fine
sl-bb20-ana>trace 199.212.134.1
Type escape sequence to abort.
Tracing the route to ns.sentex.ca (199.212.134.1)

I am guessing a blackhole, but I dont see where they told me or what list
that IP address is on... www.openrbl.org shows clean and all the box does
is outbound smtp...
Anyone else see strange things like this ?
