About this network

JSCNNET is the AS handle for Jiangsu Broadcasting Data Network Corporation Limited.

What it's used for

• The address space carries residential and business connectivity for a regional cable operator, evidenced by the netname JSCNNET and registrant IRT-JSCNNET-CN across all announced prefixes.
• The AS announces 20,992 IPv4 addresses across 4 prefixes and 1 IPv6 prefix, while maintaining only 2 observed routing neighbours. This high address-to-neighbour ratio indicates an access network providing last-mile connectivity rather than a transit provider.
• As a regional cable and broadcasting data network in Jiangsu, the traffic consists primarily of subscriber eyeballs, including broadband internet access, VoIP, and media streaming services for households and local businesses in the Nanjing area.

Notable

• All four announced IPv4 prefixes share the same netname JSCNNET and registrant IRT-JSCNNET-CN, confirming consistent ownership and management of the address inventory.
• The address inventory is concentrated in the 111.208.0.0/16 and 111.210.0.0/16 ranges, with the largest block being 111.211.192.0/18. The inventory is finely subdivided into four distinct prefixes, suggesting site-by-site or regional segmentation of the corporate estate.
