Residential RIPE
Summary
Newmedia Corporation
isp cable dsl japan
NCV is the AS handle for Newmedia Corporation, a Japanese cable and DSL internet service provider.
What it's used for
- The address space carries residential and business subscriber traffic, evidenced by reverse DNS names such as
omn.ne.jpandncv.co.jp, and netnames includingNCV-NET,TULIPNET, andOMN-NET. - The AS announces 63,488 IPv4 addresses across 12 prefixes and 1 IPv6 prefix, while maintaining 14 observed neighbours; this ratio of substantial address space to a moderate number of peers indicates an access network providing connectivity to end-users rather than a transit provider.
- Traffic from this AS consists of subscriber eyeballs accessing the internet via cable and DSL connections, consistent with the operator's business as a regional ISP in Japan.
Notable
- All registrants for the announced prefixes are listed as Japan Network Information Center (JPNIC) with the IRT contact
IRT-JPNIC-JP, which is standard for Japanese address space allocation and does not indicate a mismatch with the announcer. - The address inventory is fragmented across multiple netnames, including
NCV-CIDR-BLK-JP,NCV-NET,TULIPNET, andOMN-NET, suggesting the aggregation of address blocks from different historical acquisitions or service brands under the Newmedia Corporation umbrella.

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: 449 networks and 1,846 prefixes, as published 2026-11-03. 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.
