For an address type block you can define “Default DNS zone” under the DNS tab. The DNS zone defined in “Default DNS zone” gets automatically filled in to “DNS name(s)” field when adding new hosts to the address block.

Auto-generate Host Name

You can use the Auto-generate host name to input a pattern which will be used when creating new hosts inside the currently viewed IPAM block. Input a pattern for automatic host name generation. Use %a, %b, %c, %d to output IPv4 octets in decimal, %A, %B, %C, %D to output octets in hex.
Pattern %[0-9][rxX] can be used to generate a random element into host name. [0-9] specified the length of element, r generates numbers between 0-9, x and X generate hexadecimal numbers either in lower or upper case. For example, pattern %3r generates a random number between 000 and 999. Pattern %5X generates a 5 digit hexadecimal number in upper case.

Reverse Zones

This section assists user to quickly create corresponding reverse zone for an address type block. E.g. in block 192.168.10.0, clicking “Create reverse zone” link would bring up a page to setup reverse zone “10.168.192.in-addr.arpa.”
