www.aviationemployment.com is supposed to return 207.234.208.44, but on some ISP's people are still going to 207.234.129.253 which is our old web server that we'd like to turn off.
Most tools I have used report the domain is ok and get the new IP address.
The dnscheck tool on this site says for www that it gets a non authoritative response from A.GTLD-SERVERS.NET etc of the *old* IP address. Why is that? Should it not delegate to the primary and secondary nameservers? How can I stop that from happening? The TTL on the old IP address is coming back as 48 hours but this has been going on over a week.
