As specified in RFC1918 (ftp://ds.internic.net/rfc/rfc1918.txt) the netblocks 10.0.0.0/16, 172.16.0.0/12 and 192.168.0.0/16 have been allocated for "Private Internets". Consequently, these netblocks should not be routed over the Internet. As shown below, they are currently advertised from AS6848 and these advertisements are carried to us (AS6453) through various AS's of the SprintLink system. >sh ip bgp reg _6846$ BGP table version is 9335417, local router ID is 207.45.201.5 Status codes: s suppressed, d damped, h history, * valid, > best, i - internal Origin codes: i - IGP, e - EGP, ? - incomplete Network Next Hop Metric LocPrf Weight Path *> 10.0.0.0 144.228.164.57 0 90 0 1794 1239 1790 6846 ? *> 172.16.0.0/12 144.228.164.57 0 90 0 1794 1239 1790 6846 ? *> 192.168.0.0/16 144.228.164.57 0 90 0 1794 1239 1790 6846 ? [...] AS6846 responsibles should take immediate action to remove these announcements. SprintLink, as any conscientious operator, should take action to filter out these announcements from any of its peers.
