Summary
SK Broadband

The AS handle SKB-TBROAD_HANVIT-AS-KR is held by SK Broadband Co Ltd.
What it's used for
- The address space is registered under the netname
broadNnet-KR, indicating a broadband network operation. - The AS announces 227328 IPv4 addresses across 31 prefixes, while maintaining only 1 observed neighbour, a ratio characteristic of an access or eyeball network rather than a transit provider.
Notable
- All sampled prefixes list
IRT-KRNIC-KRas the registrant, which is consistent with the Korean National Internet Center managing the space for the operator. - The inventory consists entirely of IPv4 space with no IPv6 prefixes announced, and the address blocks are finely subdivided into /17, /18, /19, and smaller prefixes.

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: 440 networks and 1,773 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.
