Residential RIPE
Summary
Doubrava.net
isp hosting business
An AS number from the earliest era of allocation, first seen routing in 2015.
What it's used for
- A small internet provider in Czechia. 1,024 addresses in one IPv4 prefix, one IPv6 prefix, and 23 observed BGP neighbours.
Notable
- The single IPv4 prefix is
185.93.60.0/22, netnameCZ-DOUBRAVA-NET-20150324. - The IPv6 allocation is a
/29. - First observed in the routing archive in September 2015.
- One of three sampled addresses returned a name:
185-93-62-254.cust.doubrava.net.
Interesting
- The netname date and the first routing observation fall six months apart in the same year, which is the normal gap between getting address space and putting it into service. What is unusual is that both sit fifteen years after this AS number's neighbours in the sequence were issued. Numbers are reissued, so the number says nothing about the network's age.
- A
/29of IPv6 alongside a single IPv4/22is the standard allocation a regional registry hands any provider that asks. The two protocols are rationed on completely different scales, and this is what that looks like on one small network. - 23 neighbours on 1,024 addresses is a provider that peers rather than one that buys, which is how small operators get competitive paths without competitive volumes.

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: 440 networks and 1,773 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.
