Summary
JM-Networks
residential isp czech local
JMNET is operated by JM-Networks, s.r.o.
What it's used for
- The address space carries residential and business internet access, evidenced by reverse DNS entries such as
mem-176.98.253.254.jmnet.czandjmsitel254.jmnet.cz. - The AS announces 4096 IPv4 addresses across 3 prefixes and 1 IPv6 prefix, while maintaining 22 observed neighbours; this ratio indicates a local access network rather than a transit provider.
- Traffic consists of subscriber eyeballs for households and local businesses, as the operator provides internet and television services in the Czech region.
Notable
- Registrants for the 185.47.220.0/22 and 185.91.168.0/22 prefixes align with the announcer, listing JM-Networks, s.r.o.
- The 176.98.248.0/21 prefix is registered under the generic netname RIPE-NCC-MANAGED-ADDRESS-BLOCK with an unknown registrant, distinguishing it from the other blocks.
- The address inventory is composed of three distinct IPv4 blocks and one IPv6 prefix, all located in Czechia.

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 1,773 prefixes, as published 2026-10-13. 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.
