Some odd net-related messages

I just got home from (high) school, to find that I had gotten some odd
(kernel) messages during the day:

Nov 12 00:09:41 jennifer-unix kernel: ip_rt_bug: 1a174dc2 -> ae1ebacc, lo
Nov 12 00:10:32 jennifer-unix kernel: ip_rt_bug: 040029c6 -> ae1ebacc, lo
Lots of these, not always in pairs, though these were the only sets of
addresses.

1a.17.4d.c2 is a non-used address.
04.00.29.c6 is in nic.near.net.'s assigned zone, but aperantly isn't used.
ae.1e.ba.cc is also non-used.
Wait a sec. That last might be my address last night (dynamic IP), but
flopped end-for-end.

Also, I got a lot of:
Nov 12 03:52:34 jennifer-unix kernel: xmit_timer <= 0 - timer:8 when:0
Nov 12 03:52:35 jennifer-unix last message repeated 3 times
And such. These messages always seem to come in sets of 4 (one and then a
"repeated 3 times", and always within a second of each-other.

Thirdly, I get an awaful lot of:
Nov 12 15:32:46 jennifer-unix kernel: TCPv4 bad checksum from \
209.68.0.85:0000 to 204.186.30.177:0001, len=580/580/600
Note the low port numbers (dosn't always happen that way, but often). None
of the numbers are constant, but this is adversly affecting my
connectitivity. This last one has been happening for a while, but I'm
reporting it now incase its related.
Note that all packets have already been through modem-error-correction and
ppp-error-correction, so should certinly be clean by now.
