from where, maps are downloaded?

Hello
I work for a company and our internet is limited and we can use only websites which are requested beforehand and the IT team give us access of using it. For using "Online Data Source to Download" in Global Mapper, I have to have the address which Maps are download from that. I must declare the address to our  IT team, then they give me access and allow me to use online data sources.

Please let me know the exact and complete address of 'ASTER GDEM v2 Worldwide Elevation Data (1 arc-second resolution)'.
Thanks in advance.
