IPV6 PROTOCOL DEPLOYMENT IN AN INTRANET

V diplomskem delu smo predstavili skupino protokolov TCP/IP in podrobno opisali značilnosti protokolov IPv4 in IPv6 ter predstavili metode dodeljevanja naslovov IP. Prikazali smo pomanjkljivosti protokola IPv4 in natančno opisali različne tehnike, ki so bile uvedene, da bi se zmanjšala hitrost dodeljevanja naslovov IPv4 ter predstavili njegove omejitve. Predstavili smo razloge za zamenjavo protokola IPv4 po več kot 26-ih letih uporabe in prednosti IPv6. Na primeru štirih oddaljenih lokacij smo preizkusili delovanje protokola IPv6 v intranetu v načinu dvojni sklad, vse lokacije smo v del interneta, v katerem deluje IPv6, povezali tudi s tunelom IPv6. Tako smo intranetno omrežje pripravili na prehod na protokol IPv6 v prihodnosti. Uporabili smo omrežno opremo proizvajalca Cisco Systems in požarne zidove M0n0wall, ki temeljijo na odprtokodnem operacijskem sistemu FreeBSD.The senior thesis presented the TCP/IP protocol suite and described the characteristics of IPv4 and IPv6 in detail. Also the IP address allocation rules and the downsides of IPv4 were reviewed. Various algorithms that have been deployed to slow down the IPv4 address allocation were described and their limitations shown. An example of four remote locations was used to test how the IPv6 works in dual-stack mode in an intranet. All locations were connected to the IPv6 part of the Internet using an additional IPv6 tunnel. The intranet network was thus made ready for the full deployment of IPv6 in the future. Cisco Systems network equipment and the FreeBSD operating system based open source M0n0wall firewalls were used
