Summary
IdecNet
isp business hosting
A Spanish ISP with 22 neighbours behind one /19, and a reverse name that gives away its internal subnetting.
What it's used for
- Internet access and hosting. 8,192 addresses in a single
/19, one IPv6/29, and 22 observed BGP neighbours.
Notable
- The whole IPv4 inventory is
212.64.160.0/19, netnameES-IDECNET-990707. - The IPv6 allocation is a
/29, several thousand times more space than the IPv4 block it sits beside. - One sampled address answers
conelpa-broad255.idecnet.com.
Interesting
broad255is the interesting half of that name. The block announced to the world is a/19, and inside a/19an address ending.255is an unremarkable host — it is only a broadcast address if the network is internally cut into/24s. The reverse zone is describing structure that BGP never shows, which is often the only place that structure is written down at all.- Twenty-two neighbours against 8,192 addresses is a lot of adjacency for a small inventory. That ratio belongs to a provider that peers rather than one that resells transit, which is the economical shape when your customers are far from the mainland exchanges.
- The
/29of IPv6 beside a single/19of IPv4 is the whole address-exhaustion story in one inventory. The scarce resource was rationed to eight thousand addresses; the abundant one was handed over in a size that will never be filled.

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 1,775 prefixes, as published 2026-10-11. 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.
