Summary

CenturyLink (Lumen) — Fort Myers, Florida

United States · AI-generated

isp eyeball legacy

CENTURYLINK-TSDS-FLFTMY is one of a series of metro-scoped autonomous systems run by CenturyLink Communications, LLC (now part of Lumen). The TSDS element is an internal CenturyLink service code; the suffix identifies the market — here, Fort Myers, Florida.

What it's used for

  • Consumer and small-business broadband in the Fort Myers area. Reverse DNS on the address space lands in dhcp.centurylinkservices.net and embarqhsd.net, marking it as dynamically assigned subscriber access rather than servers or transit.

Notable

  • An "eyeball" network — the addresses here are homes and small offices on DSL and fibre, not hosted content.
  • embarqhsd.net ("Embarq High Speed Data") is a reminder of lineage: Embarq was the local-telephone business spun out of Sprint, which CenturyTel merged with in 2009 to create CenturyLink. Fort Myers sits in that legacy territory.

Interesting

  • CenturyLink runs a whole family of these TSDS ASNs, one per market, rather than announcing subscriber space from a single national AS. Siblings include AS4283 (Las Vegas) and AS4284 (Tallahassee).

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: 447 networks and 1,843 prefixes, as published 2026-11-02. 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.
