Sort of, but more detailled and including sub-allocations and accessible
via the whois protocol. For instance, the IANA list shows 61/8 as
allocated to APNIC but since they are a registry they are carving it up
into smaller blocks. For filtering purposes, 3/8 and 61/8 are quite
different.

If ARIN sets up their own database then it should be possible to make it
usable by RtConfig tools if there is a demand for that.
