The address is the one in your message. It was in tte response to the nslookup you copied into your message The address is from a L3 block, but is being announced by Yahoo!. We peer directly with Yahoo! in San Jose (and other places). I see no indication that Level(3) is involved in any way other than owning hte net block that Yahoo uses. I don't have IPv6 at home, but the HE looking glass also routes to an Equinix exchange and directly to yahoo and on to www.freebsd.org. If I try to trace from a Level(3) looking glass, it fails. something very odd id going on. Looks like Level(3) forgot that the address was assigned to FreeBSD and is not accepting the Yahoo! route or something similar. -- R. Kevin Oberman, Network Engineer E-mail: rkoberman@gmail.com
