i use bind8. i haven't seen any reason to upgrade to bind9
yet. bind8 has been workin goodfor years for me.

unless you want 50% dns failures you will need a backup on
another ip address. i don't know why but without a properly
configured backup(having bind listen to 2 ips won't do it)
50% of dns replies are dropped. if you only have 1 system
and get another ip, you can run 2 copies of bind one on each
ip and that will be fine. i've had this problem personally :)

i think it may depend on the registrar. i think some may
allow you to put only a dns name as a nameserver. .de may
be one, i have aphroland.de and when i do a whois it only
lists the DNS name not the ips for the nameservers.
i would highly reccomend running it on a static ip. i doubt
your domain gets much traffic? if so i can be slave for you.
or many other people on the list could im sure. DNS takes up
so little bandwidth and no effort to maintain its not a problem.
i currently host about 50 domains on my dsl connection. some
registrars(like.de) require the slave nameserver to be on
a different subnet from the primary(good practice, but not
needed for personal stuff, especially if all of the services
for that domain are on the same ip as the nameserver itself :) )
> - If not, are there free backup name server services?
probably are, i'd never use em though. your better off using
someone you know(i know you dont know me), or pay for a isp
to do it for you.

hope i helped. ive been running DNS' for about 4 years.
currently i run about 9 different nameservers in various
parts of the U.S.
also be sure your nameservers are registered. you may go
through hell down the road if they are not.
