Summary
JSMSR Network
hosting isp
Four IPv4 /24s, eighteen IPv6 prefixes, and a leased block from an address marketplace.
What it's used for
- Hosting and connectivity. 1,024 IPv4 addresses in four
/24s, eighteen IPv6 prefixes, and 26 observed BGP neighbours.
Notable
2.27.149.0/24is netnameipxo, registrantnetutils-mnt; Private Customer— a block from an address leasing marketplace rather than one of the company's own.23.162.24.0/24is registered to Aulthent, a third party again.23.177.40.0/24is netnamePRIVATE-CUSTOMER-USbut registered to JSMSR Network itself.- The IPv6 prefixes are mostly
2602:f919::/48s and/47s, with one2406:840:e180::/44from a different registry's range entirely. - Sampled reverse names read
64.40.177.23.static.jsmsr.com: the address backwards, as the reverse tree writes it.
Interesting
- Eighteen IPv6 prefixes against four IPv4
/24s is the inversion the address market produced. IPv4 has to be leased a/24at a time from whoever will rent it, while IPv6 is handed out in quantities nobody has to ration, so the same network is address-poor in one family and extravagant in the other. - Leaving the address reversed in the host name is the reverse zone's own ordering leaking into the answer. It is generated straight from the
in-addr.arpalabel without flipping it back.

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 1,772 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.
