Residential LACNIC
Summary
TUPIX
isp residential brazil telecom
AS52877 is operated by Interprime Telecomunicacoes Ltda, trading as TUPIX.
What it's used for
- The address space carries residential and business customer traffic, evidenced by reverse DNS entries such as
138-99-57-0.tupix.net.brand186-232-75-126.tupix.net.br. - The AS announces 1536 IPv4 addresses and 17 IPv6 prefixes, with 31 observed routing neighbours. This ratio of moderate address space to a significant number of peers indicates an access network providing last-mile connectivity.
- Traffic from this AS consists of subscriber eyeballs and local business endpoints, consistent with TUPIX's role as a regional telecommunications provider in Brazil.
Notable
- Registrants for both announced IPv4 prefixes (
138.99.56.0/22and186.232.74.0/23) are listed as INTERPRIME TELECOMUNICACOES LTDA, matching the AS holder. - The inventory includes two distinct IPv4 blocks and a fragmented set of IPv6 prefixes under the
2804:91c::/33range, reflecting a standard ISP address allocation.

Classification and threat
Residential Fixed-line consumer ISP. Addresses here are homes.
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 1,772 prefixes, as published 2026-10-15. 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.
