Cross Referencing Cells to input values

I am attempting to cross reference sheets to match up IPs to building names. I have attached an example. Essentially, I am trying to take column E on the TEST sheet and match it to column A on the IPs sheet. Whatever the Building Name (column B, IPs sheet) is, I want that filled into Column G on the TEST sheet. This would be a very labor-intensive process if it cannot be done automatically.

Thank you for your help!
