Summary
Algar Telecom
residential isp brazil telecom
AS25933 is operated by Algar Telecom, formerly known as Vogel Soluções em Telecom e Informática S/A.
What it's used for
- The address space carries static residential and business access, evidenced by reverse DNS records such as
177-101-208-0.static.algartelecom.com.brand187-84-200-0.static.algartelecom.com.br. - The AS announces 56,832 IPv4 addresses across 42 prefixes and 23 IPv6 prefixes, while maintaining 53 observed neighbours; this high address-to-neighbour ratio indicates an access network rather than a transit provider.
Notable
- All available RDAP registrants for the largest prefixes list "Vogel Soluções em Telecom e Informática S/A", which aligns with the AS holder name in the registry.
- The operator is widely known as Algar Telecom, reflecting a corporate rebranding from its previous name, Vogel.
- The inventory consists of multiple /21 and /22 blocks within the 177.220.0.0/16 and 189.45.0.0/16 ranges, alongside a large /18 block, indicating a substantial and fragmented address estate.

Reputation
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: 431 networks and 1,768 prefixes, as published 2026-10-12. 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.
