IXP_IRRDB_MIN_V4_SUBNET_SIZE / IXP_IRRDB_MIN_V6_SUBNET_SIZE do not work when set to 32 / 128 respectively. The expected behaviour for /32 (ipv4) and /128 (ipv6) is that prefixes of that length are accepted, but they are not due to how bird handles mask length specification.
ACTUAL RESULTS
the bird configuration filters end up with the following statements: 0.0.0.0/0{33,32} or ::/0{129,128}. These evaluate as false for /32 and /128, which is a bug.
IMPORTANCE
affects production IXPs. workaround using skins, but this is not ideal for the usual reasons.
