About this network

ASJIMMY is operated by JimmyNet s.r.o., a small internet service provider based in Ostrava, Czechia.

What it's used for

• The address space carries residential and small business internet access, as indicated by the reverse DNS record 185-211-190-254.jimmynet.cz and the netname CZ-JIMMYNET-20170705.
• The AS announces 1024 IPv4 addresses within a single /22 prefix (185.211.188.0/22) and one IPv6 prefix (2a0b:6940::/29). With only 1 observed neighbour, the low neighbour-to-address ratio confirms its role as an access network rather than a transit provider.
• Traffic from this AS consists of subscriber eyeballs for local internet access in the Ostrava region, consistent with JimmyNet's business as a regional ISP.

Notable

• The RDAP registrant JimmyNet s.r.o. matches the AS holder, confirming consistent ownership of the address space.
• The address inventory is compact, consisting of a single contiguous IPv4 block and a single IPv6 prefix, typical of a small regional operator.
