Summary
Vodafone ONO (Cableuropa)
isp legacy
ONO-AS is Cableuropa, trading as ONO — Spain's largest cable operator, acquired by Vodafone in 2014 and now registered as Vodafone ONO, S.A. The AS carries around 1.8 million IPv4 addresses.
What it's used for
- Residential broadband and telephony over ONO's hybrid fibre-coax and fibre plant. Reverse DNS on the announced space is unambiguous: subscriber addresses resolve as
…dyn.user.ono.com, the dyn and user labels marking dynamic consumer pools. - The inventory is the sort a long-lived eyeball network accumulates: several
/16s (62.42/16,81.184/16,84.123/16,84.124/16) plus dozens of smaller blocks gathered over time.
Notable
- This is an eyeball network — its address space is where subscribers sit, not where content is served. Traffic ratios and peering posture follow from that.
- Vodafone's Spanish fixed-line business was sold to Zegona in 2024, so the operating parent has changed again even though the ONO name persists in the registry and in reverse DNS.
Interesting
- ONO was assembled in the 1990s and 2000s by consolidating regional Spanish cable franchises, which is why one autonomous system ends up holding such a patchwork of unrelated IPv4 blocks. The rDNS domain has outlived two ownership changes.

Classification and threat
Residential Fixed-line consumer ISP. Addresses here are homes.
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.
