Niba utuye murugo rusanzwe, birashoboka ko ufite terefone, mudasobwa igendanwa, televiziyo ifite ubwenge, kandi birashoboka ko imashini ikina imikino yose ihujwe na interineti icyarimwe. Ibi bikoresho byose bisangiye aderesi rusange ya IP yatanzwe na ISP yawe. None, mugihe ushyizeho videwo kuri terefone yawe, nigute router yamenya kohereza videwo kuri terefone yawe kandi atari kuri TV yawe yubwenge?
Uburozi bwihishe inyuma yibi ni inzira yitwa Network Address Translation (NAT).
Abikorera hamwe na IP rusange
Router yawe ikora umuyoboro wigenga, waho imbere yinzu yawe. Igenera aderesi ya IP yihariye (mubisanzwe itangirana na 192.168 ... cyangwa 10.0 ... ) kuri buri gikoresho gihujwe na Wi-Fi. Ariko, izi aderesi zigenga ntizisanzwe kurubuga rusange.
Uruhare rwa NAT
Iyo ukanze videwo kuri terefone yawe, terefone yawe yohereza icyifuzo kuri router. Router ireba icyifuzo kandi ikora ibintu bike:
- Yandika aderesi ya IP yawe yihariye kumeza yubusobanuro.
- Isimbuza IP yihariye ya terefone yawe na aderesi ya IP rusange.
- Igenera "icyambu nimero" idasanzwe kubisabwa ikohereza kuri enterineti.
Kuri videwo ya videwo, icyifuzo gisa nkaho cyavuye muri router. Seriveri yohereza amakuru ya videwo kuri aderesi rusange ya IP ya router, yashizwemo numero yihariye yicyambu.
Gutanga ipaki
Iyo amakuru ya videwo ageze mu rugo rwawe, router igenzura nimero yicyambu ku makuru yinjira, ikareba imbonerahamwe y’ubuhinduzi, ikavuga iti: "Ah, icyambu 55432 gihuye n’icyifuzo cyatanzwe na terefone kuri IP 192.168.1.5." Hanyuma yohereza amakuru kuri terefone yawe.
Ubu buryo bwose bwo guhindura aderesi no kugenzura ibyambu bibaho muri milisegonda kumapaki ibihumbi nibihumbi buri segonda, byemeza ko abantu bose murugo babona amakuru yukuri nta nkomyi.
