after you slap me, help me! dns w/cablemodem & dhcp...

[Kevin Darcy]

First of all, you're using DHCP but do you have a *static* address? If you
don't have a static address, then it's going to be difficult if not impossible
to host your own DNS information. I've never dealt with GraniteCanyon, but
I thought they just provided a free *slave* service (someone please correct me
if I'm wrong). Trouble is, if the address of the master is subject to change
with little or no notice, GraniteCanyon or anyone else is going to have a heck
of a time being a slave to it. Not only that, but there could be security
implications -- what if the box that gets your address feeds a spoofed version
of quantifier.org to GraniteCanyon before you get a chance to inform
GraniteCanyon of the address change? To be safe, you should TSIG-authenticate
your zone transfers. But I don't know if GraniteCanyon supports that.

Secondly, I thought @home didn't want people running servers on their network.
If so, they may be blocking inbound DNS queries (conceivably they could even
block *outgoing* non-recursive queries, if they wanted to spend the cycles to
look at the RD bit of every outgoing DNS packet). You might want to verify
this.This could make hosting DNS very difficult, although of course many
things are possible through the magic of tunnelling (yuck).
