Summary

SEAC Network Solutions

United States of America · AI-generated

business isp regional infrastructure

The AS handle SEACNET is held by SEAC Network Solutions LLC.

What it's used for

  • The address space carries business and infrastructure traffic, as indicated by the netname SEACNET-IP4 and the registrant's description as a provider of advanced network infrastructure and IT services.
  • The AS announces 512 IPv4 addresses within a single prefix (64.136.64.0/23) and maintains 2 observed neighbours, a ratio consistent with a regional access or business provider rather than a large transit carrier.

Notable

  • The RDAP registrant SEAC Network Solutions LLC matches the AS holder, confirming consistent ownership of the announced space.
  • Secondary sources identify the operator as Metroplex Communications, inc. (aka METROPLEX), suggesting a rebrand or operational continuity under the SEAC Network Solutions name.
  • The inventory consists of a single contiguous IPv4 block with no announced IPv6 prefixes, indicating a focused IPv4-centric deployment.

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.
