I'm not sure it's a DNS problem as I can't ping the n900 by ip address from the XOOM. It looks like the N900 gets setup with both an IPv4 and an IPv6 address on the bnep0 interface, but the XOOM only ever gets an IPv6 address.

I'm not currently setup with IPv6 via gprs and don't know enough about the subject yet to know what my options are at this point to get everything talking. Spending my time just reading up at the moment while hoping someone can help direct me down the right path. There's a long thread about IPv6 and some links to bluetooth pan tethering on IPv6 that I'm hoping leads to an epiphany for me.
You cannot ping N900 by its IP address as it does not respond to icmp request by default. You'd have to change its behavior by setting the flag:

Code:
echo 0 > /proc/sys/net/ipv4/icmp_echo_ignore_all
Besides the IP address assignment, I'm not sure if N900's PAN supports IPv6. However, if you'd like to have the iptables accept ipv6 payload, you might have to specify it:

Code:
iptables -t nat -A POSTROUTING -o gprs0 -p ipv6 -j MASQUERADE
or it might _not_ need a specific flag for ipv6 routing, anyway, please test and feedback. Thank you! ^^
