Summary
Y K Communications
isp telecom business
A regional provider with an IPv6 allocation sized for a network many times larger than the one it runs.
What it's used for
- A rural access provider. 5,120 addresses across three IPv4 prefixes, one IPv6 prefix, and four observed BGP neighbours.
Notable
- Two blocks are netname
YKC-TEXAS, registered toY K Communications, LTD. - The third block's registry lookup failed and says nothing either way.
- The IPv6 prefix is
2604:bdc0::/32. - Nine addresses were queried for reverse DNS and none returned a name.
Interesting
- The netname names a state rather than the company's role or a block number, which is how a provider labels space when the thing worth recording is where the subscribers are.
- Four upstreams for five thousand addresses is generous. A provider serving areas with few alternatives buys its redundancy at the top of the network, because there is no second route into a town that has one road.
- IPv6 is handed out by organisation rather than by need, so a small provider receives a prefix that would serve a national carrier. It costs nothing to hold and removes address scarcity from the operator's problems permanently.

No exchange port on file. Many exchanges publish no participant list, so this is not proof of absence.
Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-10-31, 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: 447 networks and 1,843 prefixes, as published 2026-11-01. 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.
