Due to the increasing number of hosts throughout the world, the internet service providers are rolling out from IPv4 to IPv6 network. Internet cannot grow without the ISP technology. In infrastructure the network has very important role since it has the ability to control the packets that can be passed. This functionality is usually implemented an access control list (ACL) with in a router. ACLs are created from rules that define the action to be taken for any packet, this is tested and matched averse to it. If a match is made on a particular rule then the packet is either permitted to be evaluated or not true and no other rules are evaluated. This paper looks in to the effect on the slow down through a router when ACLs are implemented using an IPv6 addressing scheme. With the increase in the bandwidth of networks, the delays through networking apparatus can become significant and so, this is the main area of research. A comparison is made with alike ACLs implemented in an IPv4 and IPv6 network. More number of tests are performed in the same way using an IPv6-IPv4-IPv6 tunnel to compare the delays with the preceding results. To avoid the uncertainties related to the internet a set of experiments was conducted on a laboratory network ensuring that the comparisons are consistent.
