20.500.12556/DKUM-44400 RAZVOJ MODELA IN SIMULACIJA IZČRPANJA IPv4 NASLOVNEGA PROSTORA DEVELOPMENT OF IPv4 ADDRESS SPACE EXHAUSTION MODEL AND SIMULATION Magistrsko delo obravnava razvoj modela in simulacijo izčrpanja IPv4 naslovnega prostora. Za dodeljevanje IPv4 naslovnega prostora skrbi organizacija IANA, ki je po petih celinah sveta dodelila velike kose IPv4 naslovnega prostora. V Evropi tako za nadaljnjo razdelitev skrbi organizacija RIPE NCC, v Afriki AFRINIC, v azijsko-pacifiški regiji APNIC, v Ameriki ARIN v Latinski Ameriki in Karibih pa LACNIC. Zanimalo nas je koliko in kako je IANA razdelila IPv4 naslove po celinah in kako so regionalni razdeljevalci te naslove časovno razdeljevali naprej. Na podlagi teh podatkov smo razvili model sistemske dinamike črpanja naslovov za vsako regijo posebej. Predpostavljali smo, da bo do izčrpanja IPv4 naslovnega prostora prišlo precej zgodaj, rezultati pa so pokazali, da je pri določenih regijah še kar nekaj let rezerve. Naši rezultati so pokazali najhitrejšo izrabo IPv4 pri LACNIC (v letu 2014), kar sicer ni v skladu s pričakovanji, ravno tako pa ni v skladu s pričakovanji dinamika za AFRINIC (ki naj bi IPv4 naslove porabil leta 2017). Ostali rezultati pa so po naši oceni precej realni, ARIN naj bi IPv4 izčrpal leta 2016 oziroma 2018, RIPE NCC leta 2021, APNIC pa leta 2029. Naši podatki so primerljivi z ostalimi te vrste (primerjava z modeli Geoffa Hustona). Samo izčrpanje IPv4 naslovnega prostora še ne pomeni konec interneta, saj je bilo z uporabo IPv4 protokola kmalu vidno, da števila IPv4 naslovov enostavno ne bo dovolj za vse. Tako so zgodaj začeli z razvojem novega protokola (IPv6), ki zagotavlja dovolj veliko število IP naslovov. Thesis adresess model development and simulation of IPv4 address space exhaustion. IANA is in charge for the assignment of IPv4 address space, and it has allocated large chunks of IPv4 address space across the five world continents. RIPE NCC takes care of further distribution of IPv4 in Europe, AFRINIC in Africa, APNIC in Asia-Pacific region, ARIN in North America and LACNIC in Latin America and Caribbean. Our goal was to determine how many and in which way the IPv4 address space was distributed by the IANA for five regions and how the regional internet registries allocated these addresses in time. We have developed IPv4 address space exhaustion model and simulation for each region based on those data. We assumed that the exhaustion of the IPv4 address space will occur quite early, but the results have shown that in certain regions there is still quite a few years of reserve. Our results have shown the most rapid exhaustion of IPv4 in LACNIC (2014), which is not up to expectations just as the dynamics for AFRINIC is not up to expectations (which should exhaust IPv4 addresses in 2017). Other results are according to our estimates quite realistic, ARIN should exhaust IPv4 by 2016 or 2018, the RIPE NCC in 2021 and APNIC in 2029. Our results are comparable with other models (comparison with models by Geoff Huston). The exhaustion of IPv4 address space does not necessarily mean the end of the Internet. As it was by the usage of IPv4 protocol soon seen that the number of IPv4 addresses will not be enough for everyone. So the development of a new protocol started (IPv6), which provides a sufficient number of IP addresses. izčrpanje IPv4 naslovnega prostora RIR (regionalni internetni registrator) RIPE NCC (regionalni internetni registrator za Evropo) APNIC (regionalni internetni registrator za azijsko-pacifiško regijo) ARIN (regionalni internetni registrator za Ameriko) AFRINIC (regionalni internetni registrator za Afriko) LACNIC (regionalni internetni registrator za Latinsko Ameriko in Karibe) modeliranje in simulacija sistemska dinamika IPv4 address space exhaustion RIR (Regional Internet Registry) RIPE NCC (Regional Internet Registry for Europe) APNIC (Regional Internet Registry for the Asia-Pacific region) ARIN (Regional Internet Registry for America) AFRINIC (Regional Internet Registry for Africa) LACNIC (Regional Internet Registry for Latin America and the Caribbean) Modeling and simulation System Dynamics true true false Slovenski jezik Angleški jezik Magistrsko delo 2014-05-26 13:43:06 2014-06-23 14:00:56 2022-05-12 03:08:10 2021-04-29 03:37:14 2014 0 Kranj 0 0000-00-00 NiDoloceno NiDoloceno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 7304211 URN:SI:UM:DK:0D0BVWLG MAG_Ciber_Peter_2014.pdf MAG_Ciber_Peter_2014.pdf 1 F5941420634659F53383D80D02EB0B6D da4be481632f11074aa188f8967ebdff07bbda17652da2d448c667ff5e490465 d9dc17f9-7c0a-11eb-bb7a-00155d0001ca https://dk.um.si/Dokument.php?lang=slv&id=63761 Fakulteta za organizacijske vede 0 0 0
