About this network

The AS handle USYD-AS-AP is operated by the University of Sydney.

What it's used for

• The address space carries university infrastructure, as indicated by the netname UNISYD-AU and registrant "University of Sydney" for both announced prefixes.
• The network announces 65,792 IPv4 addresses across 2 prefixes (129.78.0.0/16 and 203.32.106.0/24) with only 1 observed neighbour, a ratio typical of an access or internal corporate estate rather than a transit provider.

Notable

• Registrants for both prefixes align perfectly with the announcer, listing "University of Sydney" and the IRT contact IRT-UNIVERSITYOFSYDNEY-AU.
• The inventory consists of one large /16 block and one smaller /24 block, reflecting a standard academic network allocation.
