Abstract
Example methods and apparatus to enable 911 services to an internet protocol ('IP') communication device are disclosed. A disclosed example method involves receiving a media access control address associated with the IP communication device and a first internet protocol address associated with a gateway through which the IP communication device is obtaining network access. A second internet protocol address associated with the media access control address is then retrieved. The first internet protocol address with the second internet protocol address are then compared. When the first internet protocol address does not match the second internet protocol address, the media access control address is associated with the first internet protocol address in a database to designate a geographic location of the device.
