Hosting Dilemma

I have just signed up with a new host with the intention of moving all my sites over to it. Something I have never considered is now confusing me and here's why.

My new host has given me the nameservers ns1.xyz.com and ns2.xyz.com (as an example, not my real nameservers), but the existing nameservers on my existing host are the same. Therefore how can the domains, when I switch them over to my new host, resolve to the nameservers on my new host considering they are the same as the existing ones?

Probably something simple but I can't think what.

Could it be that your old and new hosts are using the same outsourced DNS service?

There are other more convoluded possibilities, like the new host is actually owned by your old host (there's a few like that).

Ask the new host's support and see what they say about it.

you have a host that is a reseller, and has an account with the SAME hosting company! not only that they are using a generic 'unbranded' nameserver, one that is given out to ALL of their resellers.

what happens is that when your domain 'gets' to the nameserver...it looks to see what account has a 'flag' that their account is to service that domain.

---reseller #1 - (domain list)
/
<-nameservers-> - reseller #2 - (domain list)
\
---reseller #3 - (domain list)

you may or may not have an issue...you DO have to have the account(s) on the first 'host' deleted...and wait at least a day (or two) for the DNS to clear and the server that hosts these 2 reseller accounts to clear. you still may have to get the new host to get the server's owner to run a "dns cleanup". otherwise your domains (which will end up in the same server!) will still be directed over to the first account, and not the second.

best of luck

But it's a nameserver that I created (using one of my domains - ns1/2.mydomain.com). I signed up with my new host using that domain and they used it for my namserver.

I can't say that I understand nameservers and such that well so I am very confused. I now have a domain set up on 2 different hosts. I want it to resolve to the new host before I delete the domain from the old, but they both use the same nameservers so I can't see how this can happen.

By the way, my existing host is a reseller and my new host is a VPS.
