RE: Global view increase (was:BGP route explosion)

["Stephen J. Wilcox" <steve () opaltelecom co uk>]

We see that too

Predominantly seems to be massive amounts of /24s in a couple of nets
which were previously /16s. Culprit would appear to be AS705

*>i63.0.0.0/24      62.24.196.1                   100      0 286 209 701 705 i
*>i63.1.0.0/24      62.24.196.1                   100      0 286 209 701 705 i
*>i63.2.0.0/24      62.24.196.1                   100      0 286 209 701 705 i
.....

Lots of new /20-24 in 67.0.0.0/8 also AS705

In total AS705 is announcing 4432 new routes from yesterday.


If you're interested a copy of all new routes since yesterday is at:
