Korea, Republic of · AI-generated

pharmaceutical business corporate korea

The AS handle is BORYUNG-AS-KR and the holder is Boryung Corporation.

What it's used for

  • The space carries corporate infrastructure for a pharmaceutical manufacturer, evidenced by the registrant Boryung Pharmaceutical Co.,Ltd. and the netname broadNnet-KR.
  • The inventory consists of 256 IPv4 addresses within a single /24 prefix (123.214.181.0/24) and 0 IPv6 prefixes, with 2 observed neighbours, indicating a small internal corporate estate rather than a transit or access network.
  • Traffic from this AS consists of office workers, R&D staff, and corporate web/API endpoints for a company that manufactures and sells prescription drugs.

Notable

  • The RDAP registrant IRT-KRNIC-KR and netname broadNnet-KR align with the AS holder, confirming the space is owned by the corporation.
  • The operator changed its corporate name from Boryung Pharmaceutical to Boryung Corp. in 2022.
  • The address inventory is a single contiguous /24 block, typical of a dedicated corporate allocation.

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: 447 networks and 1,845 prefixes, as published 2026-10-31. 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.
