The incoming log on my router shows repeatedly blocking 10.20.71.1 from accessing a port? name of bootpc using udp.  What does this mean?

The other one I see repeating seems to be form my ISP (Mediacom) who apparently leases facilities from AT&T.  that is 12.201.126.113 sending TCP traffic to a port identified in the log as WWW.  Any idea why they would be doing that (whatever it is).

BTW, my router is a Linksys WRT54GL with v4.71.1, Hyperwrt 2.1b1 + Thibor15c [May 12 2006]
