About this network

WORLEY-AS-AP is registered to WORLEY Australia Inc, an APNIC Local Internet Registry with an Australian country code. What the AS actually routes, however, does not line up with the name, and this one should be treated with caution.

What it's used for

• It announces exactly one /24, 203.20.241.0/24. That prefix is not registered to Worley: APNIC records it under the netname TCR and the organisation TCR Holdings Limited, described in the registry as an ISP, with an incident-response contact registered in New Zealand.
• Its sole upstream is a small provider registered in Thailand. There are no downstream networks.
• Reverse DNS on the block is a bare, domainless placeholder of the form 203-20-241-NNN. — a dotted-quad with no suffix at all, which tells you nothing about who is using the addresses.

Notable

• The holder name, the prefix registrant and the transit path point at three different parties in three different countries. That combination — an old corporate-looking ASN, a single prefix belonging to an unrelated third party, a distant unrelated upstream, and placeholder reverse DNS — is the pattern of address space being routed on someone else's behalf rather than a company running its own network.
• These addresses should not be geolocated to the named holder, and should not be assumed to be in Australia.
• Do not assume a link to the ASX-listed engineering firm of a similar name. Nothing in the routing or the prefix registration supports it, and a familiar-looking corporate name in an ASN record is not evidence on its own.

Interesting

• APNIC has held the aut-num since the late 1990s. The number is old; the way it is being used today is not obviously connected to whoever originally obtained it.
