Summary
Telfy
isp residential mobile fiber
SKYNETLINK-AS is operated by Telfy Telecom S.L.
What it's used for
- The address space carries residential and mobile subscriber traffic, evidenced by reverse DNS entries such as
usr-0-74-101-176.telfy.comand netnames likeSKYNETLINK-NET. - The AS announces 26,880 IPv4 addresses across 33 prefixes and 39 IPv6 prefixes, while maintaining 146 observed neighbours, a ratio consistent with an access network providing last-mile connectivity.
- Traffic consists of consumer internet, mobile, fixed-line, and TV services for subscribers in specific Spanish regions including Vega Baja, Requena, and Tordesillas.
Notable
- Registrants for the majority of prefixes are Telfy Telecom S.L., though two prefixes (
185.73.96.0/22and185.187.96.0/22) are registered to Adjenet Networks SL. - The address inventory is composed of numerous /22 and /23 blocks, reflecting a fragmented allocation typical of regional ISPs acquiring space incrementally.

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.
