AS9627 TCR-AP TCR Holdings Ltd

AS9627 (TCR-AP) is held by TCR Holdings Ltd, an Australian telecommunications and hosting company registered in New South Wales. It sits behind Australian upstreams (AAPT and Vocus) and provides addressing and connectivity to a set of downstream service brands and business customers rather than operating a single mass-market network of its own.

What it's used for

The footprint is small and heavily fragmented: 72 announced IPv4 prefixes for just 31,488 addresses, with the largest a single /19 (202.9.224.0/19) and the rest a long tail of /21s, /22s, /23s and /24s spread across 202.3, 202.9, 202.182, 116.193, 122.252 and 220.247. No IPv6 is announced. Only 3 BGP neighbours are observed, so this is a customer network buying transit, not a carrier selling it.

The reverse DNS is the notable part. Sampled addresses resolve under several different organisations' domains at once: static.tcrholdings.com and user.tcrholdings.com (the holder's own), edge.w3networks.com.au and static.alphacall.com.au (two separate Australian ISP brands), and 202-3-56-5.worley.org.au (an unrelated third party). The space is therefore assigned out to distinct downstream operators and enterprise customers, each running its own naming, while TCR Holdings originates the routes.

Notable

• The static. and user. labels dominate the sample, which points at fixed business allocations rather than a dynamic residential pool.
• All the address space is APNIC-region, and every PTR maps back to an identifiable Australian operator. This is a related-party provider group with real downstream networks, not scattered inventory.
• TCR Holdings also appears against a second, separately registered ASN, so routing for the group is split across more than one AS.
