I have setup one server for multiple ips. But when I bring eth0 down and then back up I get and error of:
SIOCADDRT network is unreachable
I am not exactly sure why I am getting this message everything seems to work fine. I can access anything from this server and I can access this server from anywhere. I have noticed some collisions and transmit errors. I am not sure what would be causing this.

I'll bet that you may have eth0:0 set up as the gateway. If that is the case eth0 may not be able to see "the network". (I have seen this type of weirdness before.)
here is the output of my ifcfg-eth0 and ifcfg-eth0:0 from /etc/sysconf/network-scripts/ ifcfg-eth0 :::::::::::::: DEVICE=eth0 BOOTPROTO=static BROADCAST=10.1.4.30 HWADDR=01:10:26:19:12:B5 IPADDR=10.1.4.2 NETMASK=255.255.255.192 NETWORK=10.1.4.0 GATEWAY=10.1.4.35 ONBOOT=yes TYPE=Ethernet
ifcfg-eth0:0 :::::::::::::: DEVICE=eth0:0 IPADDR=10.1.4.1
