RKN routes for OpenVPN

Install example

Route table size optimization

RKN block many single IPs (453707 in total) and adding them all as /32 routes to table seems not a good idea.
To reduce table records, some /32 neighbors combine to /31 /30 and /29 networks, you can see them in /32 table.
Also we can align banned addresses to some larger networks, for example to /29, and than again aggregate neighbors.
The table below show stats for various cases. First is a route table size and seconds shows overhead (count of not banned IP, routed via VPN).


Some ISP blocks network requests by spoof DNS, so do not forget to add routes to your DNS server via VPN, or use dnscrypt-proxy.
