Private Nameverser Help for Dedicated Server

I'm hoping someone with some experience can help me out here.

I've just purchased a dedicated hosting server since my site has grown too big to be on shared hosting.

I'm trying to move my Wordpress site to the new host, while keeping the SAME domain name.

I went into my domain name registrar (Dynonames...interface is similar to GoDaddy's), clicked on the domain name, went into "Host Summary" and added my two nameserver entries...

ns1.mydomain.com --> 123.456.789.987 (my new dedi IP)
ns2.mydomain.com --> 123.456.789.988

I did this first thing this morning and then I went into my blog's domain name and changed THOSE nameservers to...

ns1.mydomain.com and
ns2.mydomain.com

Still, when I go to my blog, it appears to still be on the OLD reseller hosting account.

Here is where it gets strange.

When I do a "whois" on my blog, I can see that the "domain servers" listed are now, in fact:

ns1.mydomain.com and
ns2.mydomain.com

BUT the actual IP address shown is, say,

555.555.555.555 (my old reseller IP) instead of

123.456.789.987

Have I screwed something up royally or does it just need more time?

It seems like when I would change the nameservers before, it would happen almost instantly.

This seems to be taking a very long time AND the nameservers seem to be correct, it's the IP address that has not changed yet.

My site has outgrown the reseller account so Hostgator shut it down two days ago.

I'm getting anxious about having it down for so long.

Any thoughts? Thanks.

 

OK, nevermind all. I seem to have gotten it straightened out.
