SOA is a special record. As already said to read ................

you update SOA (should be only for email address if not ONLY intranet NS).

In all case if u make n update mean is needed n update. So the question is:           wy to not reflect on slave NS            if any

Increasing SN , start a NOTIFY to NS defined as slave and ALSO NOTIFY.

If n update is made and r slaves or a distribution recursive and secondary(slave) and so on, is correct to update and start a ZONE TRANSFER.

If u hve only 1 DNS at all and is not internet faced, u can decide to not update SN

Simply , the change start an incremental transer o a total transfer (depending on DNS engine on slaves NS and also notify)

Subject: SOA serial increment when we update SOA RR

When we change any resource record like A or AAAA, then SOA serial number gets incremented. But If we update only SOA record ,Is serial number of SOA remain same as before or serial number of SOA will increment?.

Do we have any RFC for this?
