AS45679 TOMOCHA-NET - Tatsumi, Tomo
Unclassified ARIN Non-Profit
Summary
Tomo Tatsumi
personal hobbyist residential ipv6
The AS handle TOMOCHA-NET is held by Tomo Tatsumi.
What it's used for
- The address space carries personal network infrastructure, evidenced by reverse DNS entries such as
host-103-167-046-064.tomocha.netand the netnameTOMOCHA-NET-SPI-CIDR-BLK-JP. - The inventory consists of 256 IPv4 addresses within a single /24 prefix and 2 IPv6 prefixes, with 5 observed neighbours, indicating a small-scale personal or hobbyist network rather than a commercial service provider.
- Traffic from this AS represents personal internet usage, including web browsing, VoIP, and general residential connectivity for the operator.
Notable
- The registrant for the IPv4 block is Japan Network Information Center (JPNIC), which is consistent with the AS holder being a Japanese individual.
- The address inventory is minimal, comprising one IPv4 /24 and two IPv6 /48 prefixes, typical of a personal allocation.

Classification and threat
Unclassified Not in the curated lists. Most of the ~80,000 allocated ASNs are not.
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: 448 networks and 1,851 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.
