Hi,
we at Cybertec have developed cast functions in C between
inet/cidr <-> bytea for a client and we would like to submit it.
This is how it works:
- IPv4 inet/cidr value will return 4 bytes if the netmask covers all 32
bits.
It returns 5 bytes if the netmask is shorter than 32 bits.
- Similarly for IPv6, 12[+1] bytes is returned.
- 4, 5, 12 or 13 bytes long bytea values are converted
to an inet/cidr value, the 5th or 13th byte is range-checked
to be a valid netmask value.
What are the requirements for it to be accepted
as a core cast function or as a contrib module?
