Well, I had about 12 hours notice the last (and first) time the IPs changed,
but with BulkRegister's excellent domain admin tools I was able to update my
registered nameserver IPs fairly smoothly and quickly.  Not so with DNS
hosts registered on Network Solutions -- changing them takes at least a
week.

The RaQ4 arrived early, so I tried out DHCP on it tonight.  Worked like a
charm, on the first try!  Small insert needed in the ifup script, no changes
needed to ifdown, copied ifcfg-eth0.master overtop of ifcfg-eth0, rebooted
and off to the races.

Here's what I added to the RaQ4 ifup script, immediately following this
comment line:

# Here's where the IP assignment flow control starts...

# DT 2001-10-04 attempt to handle DHCP
if [ "$BOOTPROTO" = dhcp -a "$ISALIAS" = no ]; then
    echo -n "Using DHCP for ${DEVICE}... "
    if dhcpcd ${DEVICE}; then
 IPSETUP=yes
    else
 echo "failed."
 exit 1
    fi
fi


So, now I just need to switch my DSL service to the 'fixed' IP plan.
