Summary
MGX Telecom
isp residential brazil regional
AS61877 is operated by MGX Telecom, a regional telecommunications provider in Brazil.
What it's used for
- The address space carries dynamic residential traffic, as indicated by reverse DNS entries such as
200-24-89-0.xd.dynamic.select.udi.br. - The network announces 2048 IPv4 addresses across 2 prefixes and 1 IPv6 prefix, while maintaining 28 observed neighbours, a ratio consistent with an access network serving end-users rather than a transit provider.
- Traffic from this AS consists of subscriber eyeballs, with the "dynamic" and "select" identifiers in the reverse DNS pointing to dial-up or dynamic IP allocation for residential customers.
Notable
- Registrants for both announced IPv4 prefixes (
186.251.72.0/22and200.24.88.0/22) are listed as MGX Telecom, aligning with the AS holder. - The address inventory is compact, consisting of two /22 blocks and a single /32 IPv6 prefix, typical for a regional ISP managing a specific geographic footprint.

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: 454 networks and 1,854 prefixes, as published 2026-11-06. 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.
