Summary

Ylem

Korea, Republic of · AI-generated

non-profit small korea

YLEM is operated by Ylem, a non-profit organization based in South Korea.

What it's used for

  • The address space is registered under the netname YLEM1-KR with registrant Ylem and administrator Young Min Kim.
  • The AS announces 512 IPv4 addresses across 2 prefixes and 1 IPv6 prefix, with only 2 observed routing neighbours.
  • As a non-profit with a minimal footprint, the traffic consists of organizational endpoints rather than commercial subscriber or transit traffic.

Notable

  • The RDAP registrants for both announced IPv4 prefixes (91.240.89.0/24 and 185.130.49.0/24) align with the AS holder, listing Ylem and Young Min Kim.
  • The inventory consists of two distinct /24 blocks and a single /48 IPv6 prefix, indicating a small, self-contained network estate.

Reputation

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: 448 networks and 1,851 prefixes, as published 2026-11-04. 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.
