What it's used for

• The address space carries residential and small business internet access, evidenced by reverse DNS entries such as 190-184-210-0.isp.cotecal.com.ar and 200-50-250-0.isp.cotecal.com.ar.
• The AS announces 9,216 IPv4 addresses across 7 prefixes and 1 IPv6 prefix, while maintaining only 3 observed upstream neighbours, a ratio characteristic of an access network rather than a transit provider.
• Traffic consists of subscriber eyeballs for fixed-line broadband services, including fibre optic connections up to 800 Mbps symmetric speeds and cable/DSL access.

Notable

• The inventory includes two /21 blocks and five /22 blocks, providing a modest but sufficient address space for a regional cooperative ISP.
