United States of America · AI-generated

cable dsl residential isp

The AS handle AIR-ADVANTAGE-ASN is held by Air Advantage LLC.

What it's used for

  • The address space carries residential broadband traffic, evidenced by reverse DNS entries such as dhcp66-84-119-254-almont.mi.airadvantage.net and dhcp64-90-210-254-ubly-south.mi.airadvantage.net which reference specific Michigan locations and DHCP assignments.
  • The AS announces 20,224 IPv4 addresses across 14 prefixes and 1 IPv6 prefix, while maintaining only 5 observed routing neighbours. This high address-to-neighbour ratio indicates an access or eyeball network rather than a transit provider.

Notable

  • Registrants are consistent with the announcer, with the majority of prefixes registered to Air Advantage LLC under netnames like AIR-ADVANTAGE and NET-216-25-176-0-1. One prefix, 68.76.152.0/23, is registered to AT&T Enterprises, LLC with the netname SBCIS-SIS80, reflecting historical infrastructure ownership.
  • The inventory consists of a mix of /19, /21, /22, /23, and /24 blocks, primarily in the 64.90.0.0/16, 66.84.0.0/16, and 216.25.0.0/16 ranges, alongside a single /32 IPv6 allocation.

Classification and threat

Residential Fixed-line consumer ISP. Addresses here are homes.

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: 442 networks and 1,779 prefixes, as published 2026-10-21. 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.
