What it's used for

• The address space carries residential and business static IP services, evidenced by reverse DNS entries such as static-64-68-224-77.ipcom.comunitel.net and 194.140.187.64.static.user.ono.com.
• The AS announces 768 IPv4 addresses across 3 prefixes with only 1 observed neighbour, a ratio characteristic of an access or eyeball network rather than a transit provider.
• Traffic from this AS consists of subscriber internet access for residential and small business customers in the Almería region of Spain.

Notable

• The address inventory is small and fragmented into three /24 blocks, consistent with a regional ISP managing a limited customer base.
