I bought a dedi , installed openvz and created 3 containers.
1st - backup vps(22.214.171.124)
2nd - private squid proxy vps(126.96.36.199)
3rd - cpanel vps(188.8.131.52)
Everything works great.
One of my customer wanted to host a .de domain which requires the 2 nameserver ips be on different subnet.
