NAT64 is an IPv6 transition mechanism that facilitates communication between IPv6 and IPv4 Ecdysis, a NAT64 gateway, includes DNS64; WrapSix, a NAT64 gateway; TAYGA, a stateless NAT64 implementation for Linux; Jool, a stateful. The Ecdysis project’s goal is to develop open-source implementations of an IPv4/ IPv6 gateway that run on open-source operating systems such as the various. WrapSix is a NAT of NAT64 – faster than kernelspace Ecdysis, faster than userspace stateless Tayga. NAT64 can be run by wrapsix command as root.

The aim ecdysjs our ecdysjs in but due to several issues it was put research was to compare the performance of the selected im- to historic status in [7]. The use of an Application Level Gateway [8] is an to analyze their behavior under heavy load conditions.

This research was supported by B. If the given server S. The client Due to the space limitations of our before mentioned sends an IPv6 packet to the received IPv6 address.

It means that by itself it can create only a see [10] and for the most accurate and detailed information, one-to-one mapping between IPv6 and IPv4 addresses. For see the relating RFCs [1] and [2].

All of these papers deal with the per- one-to-one address mapping and then it rewrites the packet to formance of a given DNS64 implementation with a given IPv6.

To sum up the findings above, we can lay down that TAYGA performed well, its memory consumption was found to be low and its response time increased approximately line- arly with the load, that is, TAYGA complied with the graceful degradation principle [23]. Evaluation of the re- sults: It increased approximately linearly with the load when the number of clients was increased from four to eight.
