Did on my Netgear and my BT Home Hub, even before I reflashed with
OpenWRT (and thus got the lovely dnsmasq). You can always run the DHCP
server somewhere more sensible and point it at the DNS server on the
router if required. I don't know anything about the Vigor or 2wire
routers (and cba Googling) but I'd be surprised if they had no way to
add hostnames for local IPs.
