I don't think inet+inet makes any sense.
I think inet+int4 should work by adding to the host address and overflowing if
it exceeds the network mask.
Ie,
10.0.0.0/24 + 1 = 10.0.0.1/24
10.0.0.255/24 + 1 => overflow
Or
10.1/16 + 1 = 10.1.0.1/16
10.1/16 + 16384 = 10.1.64.0/16
10.1/16 + 65536 => overflow
