About this network

The AS handle UOFS is held by University of the Free State.

What it's used for

• The address space carries the network infrastructure for a multi-campus public university in Bloemfontein, South Africa.
• The AS announces 198656 IPv4 addresses across 6 prefixes and 2 IPv6 prefixes, while maintaining only 1 observed neighbour, a ratio indicative of an isolated educational network rather than a transit provider.

Notable

• All RDAP registrant lookups for the announced prefixes returned UNAVAILABLE, so registrant agreement with the announcer could not be verified.
• The address inventory is dominated by the large 196.254.0.0/15 block, supplemented by smaller allocations in the 196.21.0.0/16 and 146.182.0.0/16 ranges.
