Unclassified LACNIC
Summary
CEPROMAT
government datacenter brazil state
AS28602 is operated by Centro de Processamento de Dados do Estado de Mato Grosso (CEPROMAT).
What it's used for
- The address space carries infrastructure for the state government of Mato Grosso, as indicated by the registrant name and the netname
62759. - The AS announces a single IPv4 prefix,
201.49.160.0/20, comprising 4096 addresses, with 0 IPv6 prefixes. - With only 2 observed neighbours, the low neighbour count relative to the address block suggests a limited peering footprint typical of a specific institutional or government network rather than a large transit provider.
Notable
- The RDAP registrant
CENTRO DE PROC. DE DADOS DO ESTADO DE MATO GROSSOmatches the AS holder name exactly. - The address inventory consists of a single contiguous /20 block, indicating a consolidated internal estate for the state's data processing center.

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.
