In various embodiments, techniques for identity-based address normalization are provided. A principal attempts to access a resource via a principal-supplied address. A principal identity for the principal is used to acquire one or more address patterns. The principal-supplied address is compared against the one or more address patterns and when a match is detected, the principal-supplied address is normalized according to policy associated with the matched pattern. Additional access limitations and security restrictions are then enforced in response to the normalized address.
