Need to edit the extension attributes for users. Example:  
call csv that has column of: samaccountname  
change: extensionAttribute1 to an ip: 1.1.1.1

The extension attributes are located within adsiedit for users and there are 15 extension attributes.

Your insight and help are greatly appreciated.

Use Set-ADUser and pass a hash table to its -Property (or is it -Properties?) parameter, as shown in the help file examples.
