Summary
D'LIVE (formerly C&M)
isp cable residential eyeball seoul
CNM-AS-KR is D'LIVE, the largest cable multiple-system operator in the Seoul and Gyeonggi region. It was founded in 2000 as C&M Communications — which is what the CNM handle preserves — and rebranded to D'LIVE in April 2016. It runs 17 cable broadcasting stations alongside broadband, VoIP and OTT services.
What it's used for
- Cable broadband for homes and small businesses across metropolitan Seoul and its surrounding province, bundled with digital TV, internet telephony and set-top OTT.
- Addressing for the subscriber estate — cable modems, gateways and CPE — plus the headend, provisioning and services infrastructure behind it.
Notable
- This is a large eyeball network, and the two figures that matter say so together. RIS observes a very substantial 474 IPv4 prefixes carrying 840,192 addresses — but only 9 neighbours. That combination is decisive: an operator holding the better part of a million addresses while peering with fewer than ten ASes is consuming that space, not selling it on. A wholesale carrier with that footprint would peer with hundreds.
- The prefix list is exactly what a consumer access network looks like: a handful of large aggregates (
101.235.0.0/17,49.1.0.0/17,58.143.0.0/17) plus a long tail of /19s scattered across Korean ranges, carved up regionally for subscriber pools. - No IPv6 is observed in routing, which is unremarkable for a Korean cable MSO.
Interesting
- Space here geolocates well to the Seoul capital region, but treat individual addresses as dynamically assigned consumer endpoints rather than stable hosts.

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: 442 networks and 1,772 prefixes, as published 2026-10-15. 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.
