Abstract

Address Resolution Protocol (ARP)-proxy update for roaming client devices may be provided. A client device may query for a list of active Internet Protocol (IP) addresses used by the client device. Next, the client device may determine that an Access Point (AP) supports a collaborative IP exchange function. Then the client device may send, in response to determining that the AP supports the collaborative IP exchange function, the list of active Internet Protocol (IP) addresses to the AP.
