AS15143 TOMORIN
Unclassified ARIN
Summary
Tomorin Network
hosting business
The registrant is withheld, and the netname prints the block and its prefix length anyway.
What it's used for
- A small hosting network. One IPv4
/23and one IPv6/44announced from the United States, with three observed BGP neighbours.
Notable
- The registrant field reads
Private Customer, a redaction rather than an organisation. - The netname on that same block is
NET-151-242-224-0-23, which spells out the network address and the prefix length in full. - The IPv6 prefix comes from an allocation unrelated to the IPv4 block and has no registry entry alongside it.
- Three addresses were queried for reverse DNS and none returned a name.
Interesting
- Redacting the registrant while printing the address in the netname is the recurring contradiction in this corpus. The privacy control covers the one field a human reads and leaves the mechanical one untouched, so the record withholds a name and volunteers the exact block it applies to.
- A redacted registrant means nothing can be said about who holds the space, which is different from saying nobody does. Anything treating the redaction as missing data will drop this block from a count that should include it.
- Three upstreams for five hundred addresses is generous transit for a network this size, and the IPv6 allocation is far larger than the IPv4 one, which is the usual asymmetry once a holder takes IPv6 at all.

Internet exchanges
No exchange port on file. Many exchanges publish no participant list, so this is not proof of absence.
Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-10-18, licensed CC BY-NC-SA 3.0. Transit is inferred from observed BGP paths, never declared by either party.

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: 442 networks and 1,784 prefixes, as published 2026-10-19. 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.
