Explicit proxy address for specific domain extension .gob.pe

Hi,

Our organization is requesting to disable all download of .exe and .msi files from any website except for URLs from the ".gob.pe" domain. I have read in the documentation you can create Explicit Proxy addresses with specific patterns to use as Destionation in the policy and then apply a DLP profile in it. However, I haven't been able to find if is possible to create a destionation address that would match only ".gob.pe" domains.

Please, if you have any documentation or note about how to create this address would be much appreciated.

Thanks in advance

José
