Ok, here we are. The filename of the config files proceed the settings
within:
ifcfg-eth0
GATEWAY=69.28.69.9
BOOTPROTO=none
DEVICE=eth0
MTU=""
NETMASK=255.255.255.248
BROADCAST=69.28.69.15
IPADDR=69.28.69.10
NETWORK=69.28.69.8
ONBOOT=yes
ifcfg-eth0:5
BOOTPROTO=none
DEVICE=eth0:5
NETMASK=255.255.255.248
MTU=1500
BROADCAST=69.28.69.8
ONPARENT=yes
IPADDR=69.28.69.9
NETWORK=69.28.69.8
ONBOOT=yes
ifcfg-eth0-range69
IPADDR_END=69.28.69.14
CLONENUM_START=1
IPADDR_START=69.28.69.11
ifcfg-eth0-range70
IPADDR_END=69.28.70.14
CLONENUM_START=11
IPADDR_START=69.28.70.9
ifcfg-eth0-range71
IPADDR_END=69.28.71.14
CLONENUM_START=21
IPADDR_START=69.28.71.9
I might add that I've even tried using ifconfig to assign the IPs and
the netmasks and broadcast addresses to the individual virtual devices
eth0:nn, but that has only had mixed results.

No to (nearly) all of the above. Webmin will only change the interfaces
on command, as far as I know.

Thanks for the tips.
