If you’re trying to ping something by hostname but only want to ping the IPv4 IP address, you’ll sometimes need to specify this when executing the PING command. Example on Win2008 & Vista (pinging the IP server.domain.com)
To ping and IPv4 IP:
ping server.domain.com -4
To ping an IPv6 IP:
ping server.domain.com -6
Ever tried to remove IPv6 from Windows 2008? It can’t be done through Network Connections. You can uncheck/unbind it from your NIC but to completely disable IPv6 functionality, you’ll need to set this registry key:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip6Parameters\
Create DWORD32: DisabledComponent
Value: FFFFFFFF
