Because I can ping them using either the hostname or the IP address.

Concur. But I can still ping them using the static IPs.

I thought I was but route -n shows:

Kernel IP routing table
Destination     Gateway    Genmask       Flags Metric Ref    Use Iface
192.168.100.0   0.0.0.0    255.255.255.0   U     0     0       0 eth0

192.168.100.10

See above. It looks like my gateway settings are being ignored. Here's
what route -n shows on linux (V9.3):

Kernel IP routing table
Destination     Gateway    Genmask         Flags Metric Ref    Use Iface
192.168.100.0   0.0.0.0     255.255.255.0   U     0      0        0 eth0
192.168.1.0     0.0.0.0     255.255.255.0   U     0      0        0 eth0
169.254.0.0     0.0.0.0     255.255.0.0     U     0      0        0 eth0
127.0.0.0       0.0.0.0     255.0.0.0       U     0      0        0 lo
0.0.0.0         192.168.1.1 0.0.0.0         UG    0      0        0 eth0

Observations?

You'll have to be a bit more specific.  :-)
