OACYS-INTERNET is operated by OACYS Technology.

What it's used for

  • The address space carries wireless residential and business access, evidenced by the reverse DNS entry user254-251.wireless.ocsnet.net and netnames OACYS-NET1 and OACYS-NET2.
  • The AS announces 8,192 IPv4 addresses across 2 prefixes and 1 IPv6 prefix, with 4 observed neighbours, indicating a local access network rather than a transit provider.
  • Traffic consists of subscriber eyeballs for high-speed wireless internet, VoIP phone services, and managed IT endpoints in the Central Valley region of California.

Notable

  • Registrants for both announced prefixes are listed as OACYS TECHNOLOGY, matching the AS holder.
  • OACYS Technology operates as a local full-service provider in Porterville, California, offering wireless internet, hosted voice, and IT consulting.
  • The inventory consists of two /20 IPv4 blocks and a single /32 IPv6 prefix.

Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-10-15, 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 1,782 prefixes, as published 2026-10-16. 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.
