Summary
CenturyLink Communications (legacy Embarq, Las Vegas)
isp legacy
CENTURYLINK-LEGACY-EMBARQ-LVGS is a CenturyLink (Lumen) consumer-access AS inherited from Embarq, the local-telephone business that became part of CenturyLink. LVGS is Las Vegas: this AS carries broadband subscribers in southern Nevada. It announces 64 prefixes and roughly 169,000 addresses behind a single observed neighbour.
What it's used for
Residential and small-business broadband access. The reverse DNS is unambiguous: sampled addresses across the large blocks resolve to names like nv-76-3-128-5.dhcp.embarqhsd.net and lv-67-239-192-5.dhcp.embarqhsd.net, with nv-iptv-71-50-80-5.dhcp.centurylinkservices.net on the video side. embarqhsd is the legacy Embarq high-speed-data domain, the nv/lv tags are the state and city, and dhcp is the address-assignment mechanism for subscriber lines. Tens of thousands of addresses in dynamically-assigned /19 and /20 pools is exactly the footprint of a telco DSL/fibre eyeball network.
Notable
One observed neighbour, against 169,000 addresses. This AS is a leaf hanging off Lumen's own backbone: it does not peer, it does not sell transit, it exists to originate subscriber pools. That single-upstream shape is normal for a large carrier's regional access ASes and is the opposite of the hundreds of neighbours a wholesale carrier shows.
Nearly every prefix is registered in ARIN to CenturyLink Communications, LLC under CENTURYLINK-LEGACY-EMBARQ-BKL-* handles. One exception, 192.208.23.0/24 with wapa.gov reverse DNS, belongs to the Western Area Power Administration, a federal power marketer: a carrier customer route, not third-party leased space.

Classification and threat
Residential Fixed-line consumer ISP. Addresses here are homes.
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: 447 networks and 1,843 prefixes, as published 2026-11-01. 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.
