Summary
Telxius (Telefónica)
transit backbone wholesale
Telxius (TELXIUS TELEFONICA GLOBAL SOLUTIONS) is Telefónica's international wholesale carrier, running a global IP backbone and one of the world's largest submarine-cable networks.
What it's used for
- Wholesale IP transit and capacity sold to carriers, ISPs, and content networks.
- Operating major subsea cable systems (e.g. MAREA, BRUSA, Tannat) linking the Americas, Europe, and beyond.
Notable
- This is Telefónica's international / wholesale arm, distinct from its national consumer ISPs and mobile operators (e.g. Movistar). A low announced end-user footprint is normal for a wholesale carrier.
- An IP here is usually a mid-path transit hop or carrier infrastructure, not an end user.
Interesting
- Telxius carries a large share of the Telefónica group's Latin America–Europe traffic and sells capacity on marquee transatlantic cables such as MAREA.

Classification and threat
Transit Tier-1 or major backbone carrying other networks’ traffic.
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.
