Re: DNS changes

[Kara Pritchard <kara@luci.org>]

So bish.net is your primary DNS server and bish.net's IP is changing?

So, change the IP in your config file, and it'll copy over to your 
secondary DNS server (ns1.lanscape.net) which should probably be listed as 
your primary with your registrar anyhow. When you take ns1.bish.net down, 
it should automagically look to ns1.lanscape.net which should have the 
right information because you updated your DNS and ns1.lanscape.net is 
slaving your information.

Then you need to get rid of Internic and switch to a more sane registrar, 
like us that doesn't take a week for changes.
