Hello,
I've a question... why is there a limit of two IPv4 and two IPv6 on the servers?
There is a way to overcome that limit?

Hello,
The server can have more IPs, however for configuration files e.g. for the web server / DNS there are only 2 IPs used at max with KeyHelp.

Hello,
additional information:
RIPE NCC/ARIN provide guidelines how to work with limited public IPv4 ressources.
Since webservers support SNI there is no need of multiple IP-addresses.
Old reasons like "for SSL-certificates[..]" does not judge the need of multiple IP-addresses anymore (e.g. confixx).
There are only a "few" reasonable and valid usecases to assign multiple public IP-addresses to servers.
Since the usecase of KeyHelp is "shared webhosting" there is no need for further IPs.
The option of adding two IPs(v4/v6 each) is situated on some domain registry that require at least two autoritative nameservers.
Other usecases can be covered for example by using NAT.
