Comcast contact regarding /32 nullroute
Someone/something is announcing a /32 from our IP space into comcast from a private ASN. Could someone from comcast help at least provide me some more information off-list? Normal support channels are not helping. route-server.newyork.ny.ibone>show ip bgp 74.115.212.130 BGP routing table entry for 74.115.212.130/32, version 2713438548 Paths: (13 available, best #10, table Default-IP-Routing-Table, not advertised to EBGP peer) Advertised to update-groups: 2 64650, (received & used) 68.86.80.4 (metric 69635) from 68.86.80.4 (68.86.1.4) Origin incomplete, metric 0, localpref 100, valid, internal Community: 64650:50001 no-export It should instead look like this. route-server.newyork.ny.ibone>show ip bgp 74.115.212.129 BGP routing table entry for 74.115.212.0/22, version 2674585749 Paths: (13 available, best #12, table Default-IP-Routing-Table) Advertised to update-groups: 2 29944 29889, (received & used) 68.86.1.89 (metric 66845) from 68.86.80.4 (68.86.1.4) Origin IGP, metric 0, localpref 300, valid, internal Community: 7922:89 7922:2900 Originator: 68.86.1.89, Cluster list: 68.86.1.4, 68.86.1.0 -- ~Randy
