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

Won't that just push you over the limit for an unsigned 32 bit integer, which is all that is allowed in a SOA's serial field?

YYYYMMDDnnn
