Summary

ICOnetworks

United States · AI-generated

isp legacy

ICO-SV is ICOnetworks, a regional network operator based in Salinas, California, serving the Salinas Valley and the wider Monterey Bay area. Its network operations contact is shared with the long-running local ISP got.net.

What it's used for

  • Regional internet access and hosting for the Monterey Bay region: business connectivity, fixed wireless into towns and rural areas that the large carriers underserve, plus colocation and web hosting.

Notable

  • A survivor of the independent-ISP era. Networks like this grew out of 1990s dial-up providers and stayed alive by serving geography the national carriers found unprofitable.
  • The ASN itself carries a 1994 ARIN registration date, placing the number among the early allocations even though the organisation records around it have been refreshed since.

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.
