What it's used for
- The address space carries residential and business internet access, evidenced by reverse DNS entries like
ip-201-159-107-254.xcien.comandip-45-239-70-254.xcien.com. - With 11,776 IPv4 addresses announced across 11 prefixes and only 7 observed neighbours, the high address-to-neighbour ratio indicates an access or eyeball network rather than a transit provider.
Notable
- Most registrants align with the announcer, specifically
Administradora de Servicios de Internet Sandur S.A. de C.V., thoughHuus Vas, S.A. de C.V.,Centro de Investigación en Química Aplicada, andInstituto Tecnologico de Saltilloalso appear in the inventory. - The address inventory is finely subdivided into multiple /22, /23, and /24 blocks, suggesting site-by-site segmentation or distinct customer pools within the corporate estate.

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 1,772 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.
