Summary
TKR Jasek
residential isp czechia regional
TKRJASEK is operated by TKR Jasek, s.r.o.
What it's used for
- The address space carries residential and business access traffic, evidenced by reverse DNS entries such as
pc-213-194-247-254.valachnet.cz,rez-185-214-118-254.xgbe.cz, andmail.cobbler.cz. - The AS announces 14,336 IPv4 addresses across 6 prefixes and 3 IPv6 prefixes, while maintaining 36 observed neighbours; this ratio of address space to peering partners indicates a regional access provider rather than a transit hub.
- Traffic from this network consists of subscriber eyeballs and local business endpoints, consistent with the operator's role as a telecommunications service provider in the Czech Republic.
Notable
- Registrants largely align with the announcer, with most prefixes registered to TKR Jasek, s.r.o., though one prefix (
185.214.116.0/22) is registered to FixPro,z.s. - The address inventory is composed of multiple /22 and larger blocks, including a significant /19 allocation, reflecting a consolidated regional footprint.

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: 449 networks and 1,846 prefixes, as published 2026-11-03. 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.
