What it's used for
- The address space carries consumer and corporate access traffic, evidenced by reverse DNS records such as
177-45-32-0.user.ajato.com.brand187-121-32-0.corp.ajato.com.br. - The AS announces 245504 IPv4 addresses across 19 prefixes while maintaining only 2 observed neighbours, a ratio that indicates an access or eyeball network rather than a transit provider.
Notable
- All available RDAP registrants are listed as
TELEFÔNICA BRASIL S.A, which aligns directly with the AS holder name. - The address inventory consists of large /17 blocks alongside smaller /18 through /24 subdivisions, all located in Brazil.

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: 447 networks and 1,843 prefixes, as published 2026-11-01. 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.
