Summary

SK Broadband

Korea, Republic of · AI-generated

broadband residential korea isp

SKB-SAEROMNET-AS-KR is operated by SK Broadband Co Ltd.

What it's used for

  • The address space carries residential broadband traffic, evidenced by the consistent broadNnet-KR netname across all sampled prefixes.
  • With 75,776 IPv4 addresses announced across 51 prefixes and only 1 observed neighbour, the high address-to-neighbour ratio indicates a large access network serving end-users rather than a transit provider.

Notable

  • All registrants in the RDAP sample are IRT-KRNIC-KR, which aligns with the announcer SK Broadband Co Ltd, confirming consistent ownership of the inventory.
  • The inventory consists entirely of IPv4 space with no IPv6 prefixes announced, reflecting a legacy or IPv4-centric deployment strategy for this specific AS.

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: 432 networks and 1,768 prefixes, as published 2026-10-12. 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.
