Czechia · AI-generated

isp residential czech small

ASRTYNENET is operated by Rtyne.net s.r.o.

What it's used for

  • The address space carries residential and small business internet access, as indicated by the registrant Rtyne.net s.r.o. and the netname ORG-RS396-RIPE for the primary block.
  • The AS announces 3072 IPv4 addresses across 2 prefixes (31.133.8.0/21 and 91.237.236.0/22) with only 1 observed neighbour, a ratio characteristic of an access or eyeball network rather than a transit provider.
  • Traffic from this AS consists of subscriber internet access for the local region, specifically Rtyne v Podkrkonoší in the Hradec Králové region of Czechia.

Notable

  • Registrants for the two announced prefixes differ: 31.133.8.0/21 is registered to Rtyne.net s.r.o. while 91.237.236.0/22 is registered to Rocketnet s.r.o under the netname ROCKETNET.
  • The address inventory is small and fragmented into two distinct blocks, one of which is held by a separate legal entity, suggesting a potential lease or historical acquisition.

Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-10-13, licensed CC BY-NC-SA 3.0. Transit is inferred from observed BGP paths, never declared by either party.

Classification and threat

Unclassified Not in the curated lists. Most of the ~80,000 allocated ASNs are not.

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: 436 networks and 1,771 prefixes, as published 2026-10-13. 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.
