Ambiente de simulação: implementando DNS e servidor web utilizando a técnica de transição pilha dupla

Abstract

This monograph deals with a network simulation environment, using GNS3 software, implementing one of transition techniques that currently serves a real network, called Dual Stack. Due to the increasing number of internet users the distribution of IP version 4 is running out. Besides presenting some problems that have been improved in the new version. Came the IPv6 protocol, ensuring the growth of the internet and correcting some problems of the previous version, with a number of much larger than IPv4 addresses. The chosen transition technique, Dual Stack, allows IPv4 and IPv6 protocols work simultaneously allowing the transition to the latest version to occur gradually. In addition, we also implemented the DNS server for the two versions of the protocol, simulating a corporate network with a web server. In order to demonstrate the importance of the DNS server to the version of the IPv6 protocol, because with increasing the size of the address facilitates any configuration used.
