We're currently receiving the following prefix from TeliaSonera on one
of our IP transit links in Oslo:
62.0.0.0/8 *[BGP/170] 4d 22:23:07, localpref 100
AS path: 1299 29049 I
AS 29049 is:
aut-num: AS29049
as-name: Delta-Telecom-AS
descr: Delta Telecom LTD.
descr: International Communication Operator
descr: Azerbaijan Republic
and *of course* they don't own 62.0.0.0/8.
TeliaSonera: It's about time you started implementing prefix filtering
on your customer links. Our other transit providers do this.
