isp residential korea cable

PIRANHA-AS-KR is operated by Piranha Systems, a South Korean cable and DSL internet service provider.

What it's used for

  • The address space carries residential and small business internet traffic, with all observed netnames set to PIRANHA-KR under the IRT-KRNIC-KR registrant.
  • The AS announces 15,744 IPv4 addresses across 57 prefixes while maintaining only 3 observed routing neighbours, a ratio characteristic of an access network rather than a transit provider.
  • Traffic from this AS consists of subscriber eyeballs connected via cable and DSL infrastructure in South Korea.

Notable

  • All registrant data in the sample aligns with the announcer, consistently showing PIRANHA-KR as the netname and IRT-KRNIC-KR as the registrant.
  • The inventory is composed of finely subdivided /23 and /24 blocks, primarily within the 14.206.0.0/16 and 101.250.0.0/16 ranges, reflecting a segmented corporate estate for site-by-site management.

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: 442 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.
