I bought a dedi , installed openvz and created 3 containers.
1st - backup vps(184.108.40.206)
2nd - private squid proxy vps(220.127.116.11)
3rd - cpanel vps(18.104.22.168)
Everything works great.
One of my customer wanted to host a .de domain which requires the 2 nameserver ips be on different subnet.
