Summary
SpainWISP
transit isp legacy
SpainWISP, S.L. (SPAINWISP) — a Spanish network operator based in Murcia that sells IP transit and carrier services, with wireless ISPs and small regional providers as its customer base.
What it's used for
- Transit and interconnection rather than end-user access. Its own address space is tiny (about 1,024 addresses across four
5.180.228.0/24-style blocks) and the rDNS on it is pure infrastructure:core.madrid.spainwisp.comandcore.valencia.spainwisp.comrouter interfaces, plus Google Global Cache nodes at Interxion Madrid (google.ggc.spainwisp-peer.interxion.mad…). - Customers ride their own address space behind it, which is why the AS shows a dozen downstream networks while announcing almost nothing itself.
Notable
- The ratio is the whole story: a few hundred addresses, but well over a hundred observed BGP neighbours and multiple upstreams (Lumen, Telia, Cogent). That is the shape of a transit reseller and peering aggregator, not of an eyeball network.
- Despite the WISP in the name, there are no subscriber pools here. The wireless ISPs are its customers, not its addressing.
Interesting
- Hosting Google cache nodes inside its own /24 is a small operator's way of cutting transit cost: the traffic that would otherwise be bought from a Tier 1 is served locally from Madrid instead.

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 1,783 prefixes, as published 2026-10-17. 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.
