Summary
IBSOL Telecom
telecom residential brazil
AS53205 is operated by IBSOL Telecom LTDA.
What it's used for
- The address space carries residential and business internet access, evidenced by the reverse DNS record
ip-186-235-237-254.ztitelecom.net.brwhich indicates ZTE telecom infrastructure. - The AS announces 4,096 IPv4 addresses across 5 prefixes and 23 IPv6 prefixes, while maintaining 36 observed neighbours; this ratio of moderate address inventory to a high number of peering partners suggests a regional access provider with significant transit dependencies.
- Traffic from this network consists of subscriber eyeballs and local business endpoints within Brazil, consistent with the operator's status as a telecommunications company.
Notable

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: 442 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.
