About this network
CENTURYLINK-EUROPE-LEGACY-QWEST is held by CenturyLink Communications, LLC — the carrier now trading as Lumen Technologies. The handle records the ASN's lineage: it came out of Qwest Communications' European operations and passed to CenturyLink when it acquired Qwest.
What it's used for
- Carrier address space attached to Lumen's European footprint, rather than a customer-facing eyeball network.
Notable
- One of several ASNs Lumen inherited through acquisition. Large carriers accumulate AS numbers as they absorb other networks, and the old names often survive in the registry handle long after the company that coined them is gone.
- Registered with ARIN in 1996, so the low number reflects a genuine mid-1990s allocation rather than a later reissue.
