About this network

The AS handle JACKMX is held by Roman Sartov.

What it's used for

• The address space carries amateur radio digital communications, evidenced by the netname AMPRNET and reverse DNS entries like ardc-64.jackmx.net.ua and ip-64.jackmx.net.ua.
• The network announces 512 IPv4 addresses across 2 prefixes and 1 IPv6 prefix, while maintaining 25 observed neighbours; this ratio of limited address space against a moderate number of peers suggests a small-scale access or hobbyist network rather than a large transit provider.
• Traffic from this AS consists of amateur radio operators using digital modes and data services, consistent with the registrant's identity as an individual radio enthusiast.

Notable

• Registrants align with the announcer, with Amateur Radio Digital Communications listed for the 44.30.72.0/24 block and Roman Sartov for the 91.197.70.0/24 block.
• The inventory is small and finely subdivided, reflecting a personal or club-level operation rather than a commercial enterprise.
