What it's used for

as28187.mg.stratus.com.bracross all sampled prefixes. - The AS announces 9,216 IPv4 addresses across 10 prefixes and 1 IPv6 prefix, while maintaining 26 observed routing neighbours; this ratio of moderate address space to a significant number of peers suggests a regional access network with multiple upstream transit relationships.
Notable

- The inventory is dominated by the 187.60.128.0/21 block, which is subdivided into nine smaller prefixes ranging from /22 to /24, alongside a single /20 and /22 block in other ranges.

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 1,771 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.
