recordbuilder.py is a small shell tool and library for building records for the djbdns / tinydns DNS server. It is more or less a port of the great buildRecord.cgi by Anders Brownworth that you may try out at his website.
You can find some more information about each record type over there as well.
The program requires Python >=3.5 as it makes use of ipaddress.IPv4Address.reverse_pointer (new in Python 3.5) in the aaaa function. If you do not use that function you should get away with Python >=3.3, and if you remove import ipaddress, any Py3k should be fine.
$ ./recordbuilder.py
You may create the following records:
AAAA domain address ttl
CAA domain flag tag value ttl
DOMAINKEYS domain keytype key ttl
NAPTR domain order preference flag services regexp replacement ttl
SPF domain text ttl
SRV service priority weight port target ttl
TXT domain text ttl
Run recordbuilder.py with only the record type as argument to see more info,
e.g. ./recordbuilder.py aaaa
$ ./recordbuilder.py aaaa
Usage: AAAA domain address ttl
Construct a generic AAAA record.
Arguments:
domain -- the hostname to map an IPv6 address to
address -- the IPv6 address, zero compression is supported
ttl -- time to live (int)
Returns a generic AAAA record and a PTR record.
