Abstract IPv4 is an old protocol and suffers from addresses shortage redundancy and other problems. IPv6 is a new protocol which is not been widely adopted but it supports Quality of Service QoS Features and a huge range of unique addresses. IPv6 needs to be tested and evaluated regarding to QoS support. The Differentiated Services DiffServ is a QoS framework it could be implemented in either IPv4 or IPv6. DiffServ requires 6-bit value to be assigned to IPv4IPv6 header this value is called DSCP DiffServ codepoint. DSCP is set in a ToS field in IPv4 and in a Class field in IPv6. There is no any implementation difference between assigning DSCP in either IPv4 or IPv6. In this research a comparison between IPv4 and IPv6 in adopting DiffServ framework is presented. DiffServ represents the QoS frameworks the impact of each version of IPs on QoS affects the DiffServ framework and as a result affects the whole network performance.
