Yes, especially if other computers are used with the netopia and it's in 
its default config (e.g. if a different machine picks up your old 
ipaddr, obviously you might get a different ipaddr if you subsequently 
acquire a new dhcp lease while that other machine has its lease). 

You can fiddle with a lot of settings though, I'd be surprised if you 
couldn't set things up statically one way or another.  Not sure it's 
worth the bother.  Note that if you get fed up with the 
eircom-customised dumbed-down web interface, you can telnet to it (but 
don't blame me or eircom if you break something!). The netopia boxes 
appear to have a fair few more features than are obviously exposed 
through the web interface.

[Also note that you don't have to use the embedded
DNS proxy server on the netopia - if you want to avoid IPv6 DNS 
timeouts, point your resolv.conf at an upstream DNS that doesn't hang 
in the no-AAAA record case (this includes the same eircom one the modem 
points at, so I reckon the problem's probably more on the netopia 
side...). You might then have the issue of the netopia not being IPv6 
capable anyway (dunno if eircom's network is, either)... but you'll 
avoid the waiting for DNS lookup to timeout annoyance]
