About this network

CENTURYLINK-LEGACY-EMBARQ-CLTN is one of the autonomous systems CenturyLink (now Lumen) inherited from Embarq, and it still carries consumer broadband. Registered to CenturyLink Communications, LLC in Monroe, Louisiana.

What it's used for

• Residential and small-business internet access on the former Embarq footprint.
• Announces roughly 53,000 IPv4 addresses across about 37 prefixes.

Notable

• The reverse DNS is unambiguous: addresses resolve as …dyn.embarqhsd.net and …sta.embarqhsd.net — Embarq High Speed Data, with dyn and sta marking dynamic and static subscriber assignments. This is an eyeball network, not backbone or hosting space.
• Embarq was Sprint's local telephone division, spun off in 2006 and merged with CenturyTel in 2009 to form CenturyLink. Two corporate generations later, the subscriber DNS still says "embarq".

Interesting

• Large carriers keep many acquired ASNs alive rather than renumbering customers, so a single company can hold dozens of them. When reasoning about a CenturyLink/Lumen address, the specific ASN matters: this one is broadband subscribers, while its neighbours AS6223 and AS6224 are a wholly different, federal service.
