MNAME : |
The <domain-name> of the name server that was the original or primary source of data for this zone. |
RNAME : |
The <domain-name> which specifies the mailbox of the person responsible for this zone. |
SERIAL : |
The unsigned 32 bit version number of the original copy of the zone. Zone transfers preserve this value. This value wraps and should be compared using sequence space arithmetic |
REFRESH : | A 32 bit time interval before the zone should be refreshed. |
RETRY : |
A 32 bit time interval that should elapse before a failed refresh should be retried. |
EXPIRE : |
A 32 bit time value that specifies the upper limit on the time interval that can elapse before the zone is no longer authoritative. |
