About this network

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.
