Authenticate/Attributes based on NAS-IP-Address

Using MySQL as a backend, is there any way to configure Authentication and Attribute (replies), based on the NAS-IP-Address sent to the FreeRADIUS server? Allow requests from NAS1 to authenticate and have certain attributes for users in that group and then allow requests from NAS2 to authenticate and have different attributes. Would there be anyway to allow a user to be a part of both groups? Thanks, Nick
