They are all on the same network. They are all actually the same machine -
multiple IP's bound to the same NIC on that machine.
The following is the output of ping from the FreeBSD box to the server at
24.219.44.10:
bash-2.04# ping 24.219.44.10
PING 24.219.44.10 (24.219.44.10): 56 data bytes
^C
--- 24.219.44.10 ping statistics ---
4 packets transmitted, 0 packets received, 100% packet loss
Here is the output of ifconfig:
bash-2.04# ifconfig ed0
ed0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> mtu 1500
inet 24.219.44.5 netmask 0xffffffe0 broadcast 24.219.44.31
inet6 fe80::280:29ff:fe61:c365%ed0 prefixlen 64 scopeid 0x2
ether 00:80:29:61:c3:65
Ideas??

It sound like a netmask problem. Which of the problem IPs are on the
local network, and which aren't? Likewise, do all/any of them display
the same problem?
What are the error messages from ping, and how about the ifconfig
output for the interface?
