Summary
COTAS
isp residential bolivia dsl
AS25620 is operated by COTAS LTDA., a Bolivian internet service provider.
What it's used for
- The address space carries residential broadband traffic, evidenced by reverse DNS entries such as
ip-adsl-190.180.47.254.cotas.com.boanddynamic-ip-adsl-190.186.23.254.cotas.com.bo. - The AS announces 154624 IPv4 addresses across 56 prefixes and 1 IPv6 prefix, while maintaining only 8 observed neighbours. This high address-to-neighbour ratio indicates an access network serving end-users rather than a transit provider.
Notable
- All registrants in the evidence pack are listed as COTAS LTDA., consistent with the AS holder.
- The inventory consists of multiple /18 and /19 blocks, primarily within the 190.171.0.0/16 and 190.180.0.0/16 ranges, reflecting a large allocation for a national ISP.

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 1,775 prefixes, as published 2026-10-11. 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.
