AS10022 DSLAK-AS-AP Internet access for Datacom Systems Auckland

DSLAK-AS-AP — registered with the descriptive handle "Internet access for Datacom Systems Auckland" — belongs to Datacom Group Ltd, one of the largest locally-owned IT services companies in Australasia. Datacom does systems integration, managed services, payroll software, cloud and colocation, and has been operating for over 50 years.

What it's used for

The corporate and customer-facing network of an IT services provider. The AS announces 32 IPv4 prefixes totalling 14,848 addresses and no IPv6. That prefix count against that address count is the shape worth reading: it is mostly /23s and /24s, including legacy 192.188.x and 202.x blocks accumulated over decades. Space fragmented that finely is characteristic of per-customer and per-site assignment in a managed-services estate, not the large contiguous pools an access ISP hands to subscribers.

Notable

Business / enterprise, not an ISP. The handle's phrasing is honest: this AS exists to give Datacom's own Auckland operation and its managed customers internet reachability. The single sampled PTR, mx03.datacom.co.nz, is a numbered mail exchanger — first-party service infrastructure. 7 observed BGP neighbours confirms a stub with a few upstreams; a wholesale carrier would peer with hundreds, and even a small retail ISP would show more.

Interesting

The absence of any announced IPv6 is notable for an organisation of Datacom's size and market position — it sells cloud and network modernisation while its own BGP-visible estate remains IPv4-only. Treat addresses here as corporate and managed-hosting endpoints, and expect the tenant to often be a Datacom client rather than Datacom itself.
