Dns slave server not updating

Failing to increment the serial number is the most common mistake made when updating a zone.

The first few times you make a change to a zone data file, you'll remember to update the serial number because the process is new and you're paying close attention. and none of the slaves will pick up the new zone data.

For example, you could use the eight-digit number formed by YYYYMMDD. In this form, your serial number would be 19970115.

It doesn't help that the address and pointer records are in different files, which must agree with each other.We'll go through the steps here in case you weren't the one to set up those files or if you'd just like a checklist to follow.Make these changes to your The primary master name server will load the new zone data.After modifying the zone data file becomes second nature, you'll make some "quickie" little change, forget to update the serial number . That's why you should use a tool that updates the serial number for you! Therefore, a number like 1.1 is converted to 10001 internally, and 1.10 is converted to 100010.This creates certain anomalies; for example, 1.1 is "greater" than 2, and 1.10 is "greater" than 2.1.

Every time you change the data in a zone data file, you must increment the serial number.
