Summary

The Iserv Company

United States · AI-generated

isp legacy

Autonomous System 4208 (THE-ISERV-COMPANY) belongs to The Iserv Company, LLC, an independent Internet service provider and data-center operator based in Grand Rapids, Michigan.

What it's used for

  • Internet access for homes and businesses across Michigan and neighbouring Midwest states, delivered over DSL and fiber.
  • Colocation and managed IT services out of Iserv's own Grand Rapids data center.

Notable

  • Mixed eyeball and business address space: a chunk of it is end-user broadband customers, the rest is hosted and colocated business equipment.
  • Iserv is one of the surviving mid-1990s regional ISPs. Its ARIN registration and its low AS number both date from that era, before consolidation swallowed most of its contemporaries.

Reputation

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: 448 networks and 1,849 prefixes, as published 2026-10-29. 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.
