Kanohi Whatunga - he kaiāwhina pono i roto i te hanga o ngā whatunga

I roto i te tekau tau torutoru whakamutunga kaha kei te whanake hangarau whatunga. Mai te hanganga o nga rauemi Ipurangi ao i hono ki tona maha nui o iti whatunga rohe me ngā kaiwhakamahi takitahi. I roto i tenei whakaaro, i reira ko te hiahia akiaki mo te mārama whakaahuatanga o te whakatutuki o ngā kōpuku whatunga. I kitea te otinga.

tauira TCP / IP ko te hanganga taumata-wha. Ia o enei taumata he kawenga mo ona mahi, engari tetahi o nga mahi tino nui te whakatutuki i roto i te whatunga. Hoki enei take, te whakamahi i te IP-wāhitau o te wha o nga putanga, i te mea he maha e ngā o toru tekau-rua paraire. Te reira i āta tāutu ana te whatunga, he ope ngā, me te tika, ko te wāhitau ope i te mea. Oia mau, Ko iti te maha o enei wāhitau.

mārama ki te taputapu tika mō te wāhitau tika mohio ki te wahi i roto i te wāhitau tohua e te whatunga, me te wahi i te ope. Tenei misioni e te kanohi whatunga, reira nui ohie te mahi o te tau nui o taputapu whatunga rerekē, e rua hāngū me te kaha.

āta whakatakoto Netmask e hia paraire o te wāhitau no ki te whatunga, me aha - ki te wāhitau o te ope. hanga ana tēnei hangarau taea reira ki te whakapiki ake i tino te rōrahi o wāhitau taea, i roto i te rite ki te mārama akomanga hangarau ngā ipurangiroto tataitia. Ka taea anō hoki ki a koutou te karo i tetahi pakanga puta i roto i te take o te kimi i te wāhitau taua.

kanohi whatunga taea ki te wehe whatunga nui ki te hunga iti, e kua wehea, i tahuri, ara iti, me te pera i runga i, noa haere koe i te paraire e toru tekau. Otiia ki te maha te whakanui ake o whatunga whakaiti i te maha o nga mano. Na reira, tono tenei hangarau me āta whakaaro rite te maha e tika ana o ngā wāhitau ki hostnames.

Tikanga, whakaturia te kanohi tau i iwa ki te toru tekau. Ko te maha o ngā pūāhua i roto i te tenei ā-rua wāhitau, i te kawenga mō te wāhitau whatunga. Hei tauira, mo te wāhitau 193.29.204.19, ki te te mea he kanohi whatunga 24, te wāhitau whatunga ko 193.29.204.0, ka taurima 193.29.204.1-254 wāhitau (mai te wāhitau ko te haapurororaa 193.29.204.255).

I roto i te tikanga ki te whakatau tenei katoa, he mea e tika ana ki te tātai i te kanohi whatu e hāngai ana i runga i ngā ture motuhake. I roto i te tauira i runga ake, ko tenei tukanga e whai ake. Na, te tuatahi me tatou iriti te wāhitau i roto i te pūnaha ā-rua o te tātaitanga. Ko me te meatanga na e whiwhi koe e wha octets. Me whakakapia te ngaro te mati ki ngā kore i mua i te tau. I tua atu, homai te kanohi whatunga, kaua ona tokomaha, i roto i te puka o ngā wae pātata i roto i te nui hāngai ki tenei tau reira kua tuhituhia ranei. Ko reira watea atu ki te rave i te reira e ia āta whakatutuki ahua i roto i te ahua. tuhipoka atu i runga i te wāhitau ki te wa pīhono, no ka timata te kanohi, me te mutunga wae ngā kore. Na whiwhi tatou i te maui - wāhitau whatu, te taha ki matau - te wāhitau ope. iriti i tatou hoki ki te puka-ira mua atu. Ko te katoa.

kahore he taimaha, engari tino whai hua ana tēnei mahi ka hanga whatunga whānui i runga i te tauine nui. Ka taea e kanohi whatunga riro te kaiāwhina pono mo te hanganga o te hanganga aroākapa me whakahau mārama.
