About this network

DFAT-AS-AP is operated by the Department of Foreign Affairs and Trade.

What it's used for

• The address space carries government infrastructure, identified by the consistent netname DFAT-AU across all announced prefixes.
• The AS announces 7,680 IPv4 addresses across 9 prefixes with only 2 observed neighbours, indicating a small, self-contained government network rather than a transit or access provider.

Notable

• All registrants align with the announcer, listing Department of Foreign Affairs and Trade as the administrative contact under the IRT-AUSAID-NON-AU handle.
• The address inventory is a contiguous block within the 203.6.160.0/21 range, subdivided into /21, /22, /23, and /24 prefixes, typical of a single organisation managing its own IP estate.
