Summary

The Seimitsu Corporation

United States of America · AI-generated

isp fiber regional business

SEIMITSU is operated by The Seimitsu Corporation.

What it's used for

  • The address space carries fiber internet and business technology services, evidenced by netnames such as ACC-SEIMITSU-173-245-235 and ZAYO-IDIA-318305-ZYO-209-221-62-0-23.
  • The AS announces 3328 IPv4 addresses across 7 prefixes and maintains 12 observed neighbours, a ratio consistent with a regional access provider rather than a transit carrier.
  • Traffic from this AS consists of subscriber eyeballs and business endpoints for a fiber ISP based in Savannah, Georgia.

Notable

  • Registrants for the majority of prefixes are The Seimitsu Corporation, while two prefixes (64.192.232.0/23 and 64.192.234.0/24) are registered to Epproach Communications, LLC with netnames referencing EPPROACH-SAVANNAH-MSA-3.
  • The address inventory is a mix of directly registered blocks and leased space, with netnames indicating Zayo/IDIA transit or peering relationships for some prefixes.

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: 436 networks and 1,771 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.
