Some ISP's can't find our nameservers

[snowweb]

Hi,

I'm running DA on a VPS. The domain name for DA is a subdomain eg. da.mydomain.com and I've also got the domain domain.com added as a domain under my user account.

I have 4 IP addresses, 1 is assigned to the server (shared with the hosted domains) and also shared with ns1.mydomain.com

ns2.mydomain.com is on another IP address which is also shared with a hosted domain.

I read that it is OK to share the IP address of a nameserver with a web site, correct?

My DNS records look like this:

da.mydomain.com

ftp A {IP address 1}
localhost A 127.0.0.1
mail A {IP address 1}
pop A {IP address 1}
da.mydomain.com. A {IP address 1}
smtp A {IP address 1}
www A {IP address 1}
da.mydomain.com. NS ns1.mydomain.com.
da.mydomain.com. NS ns2.mydomain.com.
mail MX 10
da.mydomain.com. TXT "v=spf1 a mx ip4:{IP address 1} ?all"

mydomain.com

ftp A {IP address 1}
localhost A 127.0.0.1
mail A {IP address 1}
pop A {IP address 1}
smtp A {IP address 1}
mydomain.com. A {IP address 1}
www A {IP address 1}
mydomain.com. NS ns1.mydomain.com.
mydomain.com. NS ns2.mydomain.com.
mail MX 10
mydomain.com. TXT "v=spf1 a mx ip4:{IP address 1} ?all"

Does the above look correct?

Should I add the entries below to either of the above zones?

ns1.mydomain.com. A {IP address 1}
ns2.mydomain.com. A {IP address 2}

When I use various online DNS report tools, I'm getting inconsistent responses.

For example, http://www.dnscolos.com/ sometimes reports the nameserver addresses as follows:

Your NS records at the parent server c0.info.afilias-nst.info are:
ns1.snowweb.info [87.119.195.66] (which I have no idea where that IP came from!)
ns2.snowweb.info [{IP Address 2}]

Other times, it seems to use a different parent server and get the correct IP's:

Your NS records at the parent server a9.info.afilias-nst.info are:

ns1.snowweb.info [{IP Address 1}]
ns2.snowweb.info [{IP Address 2}]

When I do an nslookup from my home DSL connection, I get the following:

< * * * COMMAND WINDOW * * * >

C:\>nslookup ns1.mydomain.com
Server: ns1.i-gate.net
Address: 58.69.254.140

*** ns1.i-gate.net can't find ns1.mydomain.com: Non-existent domain

< * * * COMMAND WINDOW * * * >

However, when I nslookup mydomain.com it returns correctly with {IP Address 1}

Any pointers (no pun intended) would be greatly appreciated!

Thanks.

Sorry to trouble you guys. I've solved this now by adding the following:

ns1.mydomain.com. A {IP address 1}
ns2.mydomain.com. A {IP address 2}

Thanks anyway.
