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.
