You would have to make sure all admins had static IP addresses, never had to login from their mobile phone, and never used wifi while on the road.

Your best bet is to activate two-factor authentication. Discussion and directions can be found starting on page 43 of the Implementation Guide found in the docs folder's PDF file.

Great security without the "what's my IP now" problem.
