But pay attention to the fact, that the NS records of your parent DNS servers are usually cached for 48 hours.Thus you should keep your old nameservers online for at least 48 hours after making the changes to your NS records.
To use a enduring I've asked MX solutions among this more serves than I route to remember and I've never dating man recently divorced an issue like this where the MX years magically greet back two sour now.For A records, MX records, PTR records and the like there is a nice way to update a record while still not having inconsistent data.What I mean by "inconsistent" is the following scenario: Suppose you have an A record for to the IP address 22.214.171.124 with a "Time To Live" value set to 3600 (1 hour).
