The AS handle AS27837 is held by Dialnet de Colombia S.A. E.S.P.
What it's used for
- The address space carries residential and business access traffic, consistent with the operator's identity as a Cable/DSL/ISP provider in South America.
- The network announces 15104 IPv4 addresses across 14 prefixes and 1 IPv6 prefix, while maintaining only 5 observed neighbours, a ratio that indicates an access network rather than a transit provider.
Notable
- All registrants for the announced prefixes match the announcer, identified uniformly as Dialnet de Colombia S.A. E.S.P.
- The address inventory is composed of one large /19 block and thirteen smaller /21, /22, /23, and /24 blocks, reflecting a fragmented but cohesive corporate estate.

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 2026-10-18, licensed CC BY-NC-SA 3.0. Transit is inferred from observed BGP paths, never declared by either party.

Classification and threat
Unclassified Not in the curated lists. Most of the ~80,000 allocated ASNs are not.
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: 443 networks and 1,784 prefixes, as published 2026-10-19. 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.
