About this network
AS27845 is operated by Empresa de Recursos Tecnologicos S.A E.S.P (ERT).
What it's used for
- The address space carries residential broadband access, evidenced by reverse DNS entries such as adsldynamic-car-254-187.ert.com.co and pppoe.dyn.car.ert.com.co.
- The AS announces 19,712 IPv4 addresses across 21 prefixes and 1 IPv6 prefix, while maintaining only 6 observed neighbours. This high address-to-neighbour ratio indicates an access/eyeball network rather than a transit provider.
Notable

- The address inventory is finely subdivided into multiple /22 and /24 blocks within the 190.6.0.0/16 and 190.97.0.0/16 ranges, reflecting site-by-site segmentation typical of a regional ISP.
