About this network

The AS handle TAC-NET is operated by Tokoname New-TV Corporation.

What it's used for

• The address space carries residential cable television and internet access, evidenced by reverse DNS entries such as catv396000.tac-net.ne.jp and catv443254.tac-net.ne.jp.
• The network announces 20,480 IPv4 addresses across 5 prefixes and 1 IPv6 prefix, while maintaining only 1 observed neighbour, a ratio indicative of an access or eyeball network rather than a transit provider.

Notable

• All RDAP registrants for the announced prefixes are listed as Japan Network Information Center (JPNIC), which is consistent with the standard allocation process for Japanese ISPs and does not indicate a mismatch with the announcer.
• The inventory consists of five /20 IPv4 blocks and one /40 IPv6 block, all located in Japan, with netnames consistently referencing TAC-NET.
