Folks,

I wanted an answer to a simple question about network 1/8 that netcom is
routing today. But, netcom has no obvious phone number for a noc.

We default out esnet and thus the following traceroute:

Looks like they have a little problem in chicago.

Domain servers in listed order:

NETCOMSV.NETCOM.COM 192.100.81.101
NS.NETCOM.COM 192.100.81.105

But, that number gets you into trying to find someone to talk to by punching
numbers, non of which are appropriate.

We are getting a number of probes from various network 1 host
address. As well as generating some packets with network 1 source addresses
ourselves. (these are now blocked, we try to only send packets from networks
we are responsible for)

Anyone have an idea what is causing this? Should I be worried?

Thanks,

Phil
