dns problem

[smmwizard]

Hi

I have a dedicated server with 30 site.
Some of that sites can visit his site but some of them can't visit.
Some of state in our country can visit all site but some other state can't visit that site.

I check many of my server's setting. I think it's from my name sever.

When i try nslookup i see:

[mostafa@localhost ~]$ nslookup server ns1.dpvhost.com
Server: ns1.dpvhost.com
Address: 91.98.29.194#53

I have a dedicated sever manage with directadmin and OS: CentOS and i setup 30 site in.

a domain for example http://www.khorasanprisons.ir:
Some location in our country can see this site but some other location can't see this site.

I tried many solution but i could't find any resolve.

I think this is dns problem. this domain's ns records is ns1.dpvhost.com and ns2.dpvhost.com.

when i try to nslookup for ns1.dpvhost.com i see:

[mostafa@localhost ~]$ nslookup server ns1.dpvhost.com
Server:		ns1.dpvhost.com
Address:	91.98.29.194#53

http://intodns.com/dpvhost.com

it looks ok to me other then the no glue DNS issue.

I would guess it's an ISP issue with slow updating DNS servers.... athough you do have the TTL set at the higher end it looks like.

I can see all site always.
Then why can't i nslookup for ns1.dpvhost.com. we had this problem during last 3 weeks.

My testing shows no problems. So I presume you've got it fixed.
