Hosting ARIN
Summary
Lumen / CenturyLink (legacy Savvis)
backbone transit hosting
A large legacy US backbone Autonomous System (CENTURYLINK-LEGACY-SAVVIS),
now part of Lumen Technologies via CenturyLink's acquisition of Savvis. Savvis
was a major managed-hosting and IP-network operator; this ASN carries that
inherited transit and hosting infrastructure.
What it's used for
- Long-haul IP transit and enterprise connectivity, plus legacy managed hosting and data-center customers absorbed from Savvis.
Notable
- Primarily a carrier/backbone ASN, so addresses here are often transit or enterprise circuits rather than retail VPS.
- Part of the broader Lumen/CenturyLink/Level 3 network family, which spans many ASNs from decades of mergers.
Interesting
- Savvis was one of the early managed-hosting and colocation heavyweights before CenturyLink (now Lumen) acquired it in 2011.
