wireless isp residential business

The AS handle MAXWIRE-001 is held by Maxwire, Inc.

What it's used for

  • The address space carries wireless internet service for homes and businesses, evidenced by reverse DNS entries pointing to private.maxwire.net and registrant netnames MAXWI-2019 and MAXWIRE1.
  • The network announces 2048 IPv4 addresses across 2 prefixes (142.202.108.0/22 and 208.73.228.0/22) with only 2 observed neighbours, indicating a local access network rather than a transit provider.
  • Traffic from this AS consists of subscriber eyeballs for residential and small business customers in Illinois, served via wireless technology.

Notable

  • Registrants for both announced prefixes are MAXWIRE, INC., matching the AS holder.
  • Maxwire is a small, unfunded wireless internet provider based in Illinois, serving approximately 17,000 households in a single state.
  • The inventory consists of two /22 blocks, a modest footprint consistent with a regional wireless 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: 449 networks and 1,846 prefixes, as published 2026-11-03. 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.
