Subject: [dns-operations] Recommended zone serial number format for over 100 changes / day

Hi DNS Gurus,

RFC1912 recommends the following SOA serial number format: YYYYMMDDnn

However, this does not support more than 100 updates per day (whilst this sounds like a lot, the fluidity of the Cloud means there are some applications where large numbers of changes are commonplace).

Is there a recommended serial format that supports large numbers of changes?

Thanks in advance,

Jonathan Tuliani
