AS12508 AS12508 Bratislava, Slovak Republic
Residential RIPE Cable/DSL/ISP
Summary
Rainside
isp hosting business
A Slovak provider with 31 neighbours for 8,704 addresses, and an AS name that is its own number plus a city.
What it's used for
- Internet access and hosting. 8,704 addresses in two IPv4 prefixes, one IPv6
/29, and 31 observed BGP neighbours.
Notable
- The AS handle reads
AS12508 Bratislava, Slovak Republic— the number repeating itself, then a location. 212.89.224.0/19is netnameSK-RAINSIDE-20000519, registered to Rainside s.r.o.164.40.168.0/23belongs to a different company, DCBA s.r.o., under netnameSK-DATACUBE-20111116.- An address in that second block answers
ptr126.169.data-cube.sk, spelling out the last two octets in reverse order behind the literal stringptr. - The IPv6 allocation is a
/29, the size given to a provider expected to hand out/48s.
Interesting
- Thirty-one neighbours against 8,704 addresses inverts the usual ratio. A network with this little space and this many adjacencies is not selling access to those addresses; it is peering, which in a single-city market means turning up at the local exchange and swapping routes with everyone else who did.
- The eleven years between the two netnames,
20000519and20111116, span the gap between a/19issued when space was still handed out generously and a/23issued when it was not. The second block is a sixteenth the size of the first.

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: 445 networks and 1,817 prefixes, as published 2026-10-27. 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.
