efficient use of IP address space allocations by providing appropriate
documentation, including assignment histories, showing their efficient use.
ISPs must provide reassignment information on the entire previously allocated
block(s) via SWIP or RWhois server for /29 or larger blocks. For blocks
smaller than /29 and for internal space, ISPs should provide utilization data
either via SWIP or RWhois server or by using the table format described in
