Summary

CenturyLink Communications (Lumen)

United States · AI-generated

enterprise legacy

CENTURYLINK-SPA-ZUNI is registered to CenturyLink Communications, LLC, now part of Lumen Technologies. It is one of the carrier's internal-use autonomous systems, not the backbone that carries its customers.

What it's used for

  • Every prefix it announces sits inside ARIN blocks named CENTURYLINK-LEGACY-QWEST-IT-BLK-*: 155.70.0.0/16 fragments, 148.156.128.0/21 and 199.168.32.0/24. These are Qwest-era corporate IT ranges that CenturyLink inherited.
  • What little reverse DNS exists still resolves under qwest.net, confirming the space is company infrastructure rather than subscriber or transit addressing.

Notable

  • Do not read this as CenturyLink's eyeball or transit network. Those live on other, much larger AS numbers; AS7359 is an internal IT AS with a few thousand addresses.
  • The SPA-ZUNI part of the handle is an internal CenturyLink/Qwest designation with no public expansion, so it is best treated as a label rather than a location or product.
  • ARIN registered the ASN in November 1996, during the Qwest/US West era that preceded the CenturyLink and Lumen names.

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: 454 networks and 1,852 prefixes, as published 2026-11-08. 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.
