Recently our company switched from Embarq to Comcast for all of our phone, computer and TV connections. Now I can't access the internet or our companies network.
Where can I find an IPP address?:confused:

The IT staff at your company should provide the necessary info for any changes that need to be made on your computing devices.

As Scleros said you need to be discussing this with your IT support staff. An IP address is generally assigned when you connect to a network.
