Summary
Soluciones Dinamicas de la Red, S.L. (SDR)
hosting legacy
SDR is Soluciones Dinamicas de la Red, S.L., a small Spanish internet services company registered in Pozuelo de Alarcon, on the outskirts of Madrid.
What it's used for
- Internet and hosting services. One announced block is a provider-independent
/24whose registry record describes it plainly as "Internet services provider"; the other is a/22documented as internet hosting services. - The network is tiny: roughly a thousand addresses across two prefixes, with a couple of upstreams and no significant peering footprint.
Notable
- Abuse handling and one of the maintainers point at Tecnocratica, a Madrid data-centre and hosting operator, which is also an upstream. That relationship suggests SDR's presence is inside a Madrid colocation facility rather than an access network of its own.
- The administrative and technical contact is a single named individual, which is typical of long-lived one- or two-person Spanish network operators that predate the consolidation of the local hosting market.

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 1,771 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.
