Summary
XTRA Telecom
isp mobile telecom business
Eight hundred thousand addresses, four brands, and three spellings of the same abuse contact.
What it's used for
- A telecoms group's network. Two hundred and fifty-two IPv4 prefixes and twenty-five IPv6 prefixes announced from Spain, eight hundred and thirty-five thousand addresses, across ninety-two observed BGP neighbours.
Notable
- The blocks carry netnames from at least four different brands, including a mobile operator, a fixed operator and a cable company, all under one number.
- The group's abuse contact appears three ways across those blocks: as one word with no separator, as three words with spaces, and as a company abbreviation followed by the registry's name.
- One netname is the block's own address with the dots replaced by hyphens, in mixed case, and the same netname is used for two different blocks.
- One block lists only an abuse contact, with no company at all.
- The single answering address returns a name with no address in it, shared across the range.
- Eighteen addresses were queried and one returned a name.
Interesting
- Three spellings of one abuse contact is what a merger does to a registry. Each acquired company's blocks got the new owner's contact written in whatever form the person doing the editing used that day, and nothing ever normalised them.
- A netname made of the block's own address is redundant while it is right and misleading the moment the block is split, which here it already has been.

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: 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.
