About this network
SKTELINK-AS belongs to SK Telink, the SK Telecom subsidiary that launched in 1998 with the 00700 international dialling brand and now also sells international SMS, internet telephony, satellite maritime communications, corporate lines, and the SK 7mobile MVNO.
What it's used for
- The company's own telecom service platforms and the address space behind its fixed and value-added services, rather than a general-purpose ISP business.
Notable
The pack shows 47 announced IPv4 prefixes carrying 83,712 addresses — including three large /18 aggregates (211.173.192.0/18, 211.39.0.0/18, 210.219.64.0/18) — with no IPv6 and five observed BGP neighbours.
Five adjacencies is the number that decides the kind. It is more than a plain enterprise needs and far fewer than a carrier would have: SK Telink is multi-homed into several Korean carriers because its voice and messaging platforms must reach every network well, not because it sells transit onward. A wholesale carrier sitting on 83,000 addresses would show peers in the hundreds.
Confidence is low on use, deliberately. The obvious guess — that this is SK 7mobile subscriber space — is probably wrong: 7mobile is an MVNO riding SK Telecom's radio network, so its handsets are far more likely addressed out of the host operator's pools than out of this AS. The 83k addresses are better read as SK Telink's own legacy fixed-line and service allocations, dating from its late-1990s origins, but nothing in the pack independently proves what sits in the big /18s.
Interesting
- The 00700 prefix is one of the most recognised telecom brands in Korea, and this AS is the internet-side plumbing of the company behind it.
