dns_soa view: Add documentation under Xfer field
I tried to transfer a DNS zone to a different server with the Xfer value left empty, but the transfer was aborted. After checking the logs I found the Xfer value should be filled with the permitted IP addresses. (This wasn't necessary in ISPconfig2.)
I think this field should be documentated (just like the fields DNS zone, primary NS and mbox have) for the possible values the Xfer value can have:
(empty) = zone transfer not allowed
- = allow every server to transfer the zone Values should be comma-seperated. Accepted values:
- IP address
- CIDR-formatted range
- Network/netmask
