Summary

Fast-Air Internet

United States of America · AI-generated

isp fixed-wireless rural residential

The AS handle FAST-AIR is held by Fast-Air Internet, Inc.

What it's used for

  • The space carries fixed-wireless broadband access, evidenced by the netname FAII-NET and reverse DNS records pointing to fast-air.net.
  • The network announces 2048 IPv4 addresses within a single prefix (198.21.88.0/21) and maintains 2 observed neighbours, a ratio consistent with a local access provider rather than a transit carrier.
  • Traffic consists of subscriber eyeballs for residents in Iron County, Michigan, and Northern Wisconsin, serving approximately 13,000 people with high-speed broadband.

Notable

  • The RDAP registrant Fast-Air Internet, Inc. matches the AS holder, confirming consistent ownership of the address space.
  • The address inventory is compact, consisting of a single /21 block, which aligns with the scale of a regional rural ISP.

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.
