Summary
American Data Networks
business isp costa-rica static
AS27876 is operated by American Data Networks, a Costa Rican internet service provider.
What it's used for
- The address space carries static business connectivity, evidenced by reverse DNS entries such as
static.200.0.americandatanetworks.comandstatic.164.0.americandatanetworks.com. - The AS announces 13,312 IPv4 addresses across 6 prefixes with only 2 observed neighbours, a ratio indicative of an access or eyeball network rather than a transit provider.
Notable
- Registrants for the smaller prefixes include Cogent Communications, LLC, INFORMATION TECHNOLOGIES OUTSOURCING, and H.B. Fuller Company, while the largest block's registrant data was unavailable.
- The inventory consists of a mix of larger blocks like
190.7.192.0/19and smaller /24s, with no IPv6 prefixes announced.

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 1,782 prefixes, as published 2026-10-16. 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.
