RE: [isp-bgp] /32 in RouteViews
This is a no-no I believe.. Whoever is sending them should have a filter to
restrict themselves from sending /32s, but I just have a filter to reject
incoming /32s since I don't want them to clog my memory.

Subject: [isp-bgp] /32 in RouteViews

What is the significance of /32s in in the RouteViews data?  Is this an
artifact from the peering process?  Is it the peer that is sending the
routes?  I can't find a good explanation anywhere.

Some examples:
