Summary
Empresa de Recursos Tecnologicos
residential isp colombia adsl
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
adsl_dynamic-car-254-187.ert.com.coandpppoe.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
- All registrants for the sampled prefixes match the announcer, consistently listed as
Empresa de Recursos Tecnologicos S.A E.S.P. - 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.

Internet exchanges
No exchange port on file. Many exchanges publish no participant list, so this is not proof of absence.
Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-10-13, licensed CC BY-NC-SA 3.0. Transit is inferred from observed BGP paths, never declared by either party.

Classification and threat
Hosting Datacenter or cloud provider. Addresses are servers, not people.
Spamhaus DROP
Not on ASN-DROP The network as a whole is not listed.
No DROP prefixes None of its announced space is on the DROP prefix list.
Spamhaus DROP ("Don't Route Or Peer") lists space and networks run by, or hijacked for, spam and cybercrime operations: 442 networks and 1,773 prefixes, as published 2026-10-13. A short, high-confidence list, so a match is worth taking seriously, and absence from it says little on its own.
FBI IC3
No IC3 indicators Nothing from the FBI IC3 feed.
IC3 threat data is alpha. Absence of an indicator is not evidence of good behaviour, only of absence from this one feed.
