Summary
SK Telink
business telecom south-korea
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
00700prefix is one of the most recognised telecom brands in Korea, and this AS is the internet-side plumbing of the company behind it.

Interconnection
Peering at a glance
Internet exchanges
No exchange port on file. Many exchanges publish no participant list, so this is not proof of absence.
Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-10-13, licensed CC BY-NC-SA 3.0. Transit is inferred from observed BGP paths, never declared by either party.

Classification and threat
Unclassified Not in the curated lists. Most of the ~80,000 allocated ASNs are not.
Spamhaus DROP
Not on ASN-DROP The network as a whole is not listed.
No DROP prefixes None of its announced space is on the DROP prefix list.
Spamhaus DROP ("Don't Route Or Peer") lists space and networks run by, or hijacked for, spam and cybercrime operations: 436 networks and 1,771 prefixes, as published 2026-10-13. A short, high-confidence list, so a match is worth taking seriously, and absence from it says little on its own.
FBI IC3
No IC3 indicators Nothing from the FBI IC3 feed.
IC3 threat data is alpha. Absence of an indicator is not evidence of good behaviour, only of absence from this one feed.
