About this network

AS18734 is operated by Operbes, S.A. de C.V., the corporate entity behind the Bestel internet service provider.

What it's used for

• The address space carries residential and business customer traffic, evidenced by reverse DNS entries such as static-187-164-72-0.bestelclientes.com.mx and static-187-164-4-0.bestelclientes.com.mx.
• The AS announces 205,448 IPv4 addresses across 444 prefixes and 4 IPv6 prefixes, while maintaining 109 observed neighbours; this high address-to-neighbour ratio indicates an access network serving end-users rather than a transit provider.
