Strange thing with nameservers...

[Alessandro]

Hello to everybody,

Admin: I didn't place a TT because I believe it's a DNS problem that it will solve itself in the next hours. Probably my last 2 TT have this cause.

I wonder if someone else is having such an issue.

Yesterday I registered 2 domains (.it) and received the following error from NIC's AutoCheck:
"Error - The NS server NS.INTEGRADNS.COM does not seem to have a valid IP number"
Same thing for the slave (both are mapped to NS/NS1.HSPHERE.CC). After several queries I found out that several name servers on the net map my NS with these IP's: 216.157.130.154 and 216.157.130.206. Some name servers have one wrong and one correct IP, so I think the situation is coming back to normal.

My question is: how come these wrong IP's propagated? Anyone has an idea?

Thank you for any light...


Here are the queries I did just for now to several nameservers:

Italian NIC (DNS3.NIC.IT)
NS.INTEGRADNS.COM -> 216.157.130.154
NS1.INTEGRADNS.COM -> 216.157.130.206

Registrant's (name-s1.phoenix.it)
NS.INTEGRADNS.COM -> 216.157.130.154
NS1.INTEGRADNS.COM -> 216.157.130.206

Vortech's
NS.INTEGRADNS.COM -> 65.57.231.100
NS1.INTEGRADNS.COM -> 65.57.231.120

Found out that my maintainer pulled a backup wiith matrix's old NS IP's.
The problem is that as today, after a week that the IP's were corrected, still several NS on the net have the old IPs (one or both), so I cannot transfer zones for my new domains.

Shouldn't be a week enough for propagation?

I've had a very similar problem - After lots of hair pulling moments, found the error was caused by my domain registrar.

In fairness to my Domain registrar they solved the issue very quickly.

Thanks Garreg, I'm getting towards the same solution.
I just found that after I changed the IPs at my registrar's CP (at least 3 times in the last week...) gTLD parental servers aren't updated.

I just called them and now I'm waiting.
