AS10116 HTCL-WAP-HK-AP Hutchison Telephone Company Limited

HTCL-WAP-HK-AP belongs to Hutchison Telephone Company Limited, the operator of 3 Hong Kong, CK Hutchison's mobile carrier. The WAP in the handle is the giveaway: this AS was registered for the Wireless Application Protocol gateway estate, the walled-garden proxy layer through which early mobile handsets reached the internet.

What it's used for

A single, narrowly scoped slice of 3's mobile infrastructure. The AS announces exactly one IPv4 prefix — 203.145.64.0/21, 2,048 addresses — and no IPv6. One /21 and nothing else is not a general-purpose carrier network; it is a dedicated function block. Addresses in this range should be read as operator-side mobile infrastructure and the gateway/NAT pool sitting in front of it, rather than as an ordinary subscriber pool.

Notable

This is mobile-operator space, though a specialised corner of it. The single observed BGP neighbour shows the AS is single-homed, almost certainly through Hutchison's own main network rather than to the wider internet directly — a strong sign of an internal-function AS rather than an independent network. The bulk of 3 Hong Kong's actual mobile data customers ride [AS10118](https://asn.ipinfo.app/AS10118), the Internet Access Service AS, which carries forty-five thousand IPv4 addresses and a large IPv6 estate.

Interesting

WAP as a consumer technology is long dead, but the AS number, the /21 and the handle all survive it. Registry handles routinely outlive the products that motivated them, so treat WAP here as a historical label on live Hutchison mobile infrastructure, not as a claim about what the addresses do today.
