Residential RIPE
Summary
Salt Mobile
mobile telecom isp business
Ninety-eight thousand addresses in two routes, one of them still named after the brand the company used to have.
What it's used for
- A mobile operator's network. Two IPv4 prefixes and one IPv6
/29announced from Switzerland, ninety-eight thousand three hundred and four addresses, across a hundred and twenty-nine observed BGP neighbours.
Notable
- The whole IPv4 footprint is a
/16and a/17, announced whole with nothing broken out of them. - One netname is a country code and the current brand, with no date. The other is a country code, a previous brand and a date from the year two thousand.
- The holder string prefixes the current brand with a country code before repeating the company name.
- The IPv6 allocation is a
/29, the size given to operators expected to number a whole subscriber base. - A hundred and twenty-nine neighbours is heavy interconnection for a network announcing two routes.
- Six addresses were queried for reverse DNS and none returned a name.
Interesting
- Two routes for a hundred thousand addresses is the opposite of what most operators this size do. Every other network here is split into dozens of pieces; this one has kept its announcements whole, which is easier on everyone else's routers and takes discipline to maintain.
- A netname is the only field nobody has to update after a rebrand, so it is often the last place the old name survives. Here it has outlasted two changes of owner.

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: 432 networks and 1,768 prefixes, as published 2026-10-12. 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.
