Pehea e hoʻohana ai i kahi helu IP no ka huliʻana i kahi helu MAC

Hoʻohana kaʻenehana kikowaena TCP / IP i nā adiresi IP a me nā helu MAC o nā pūnaewele'ōpili i pili. ʻOiai ka hoʻololiʻana o ka IP IP i ka manawa,ʻo ka helu o ka MAC o kahi mea hoʻopuka pūnaewele e noho mau like ia.

Aia kekahi mau kumu e makemake aiʻoe eʻike i ka helu MAC o kahi polokalamu mamao, a he mea maʻalahi ke hanaʻana ma o ka hoʻohanaʻana i kahi pono o nā laina kauoha , e like me ke kauoha Prompt in Windows.

Hiki i hoʻokahi polokalamu ke loaʻa nā'enewa kikowaena a me nā helu MAC. ʻO kekahi'ōpona laptop me ka Ethernet , Wi-Fi , a me nāʻoihana Bluetooth , no ka laʻana, loaʻaʻelua mau a me ka MAC e pili ana me ia, hoʻokahi no kēlā me kēia pūnaewele pūnaewele.

No ke aha e hōʻike ai i kahi helu MAC?

Nui nā kumu no ka hahaiʻana ma lalo o ka helu MAC o kahi mea pūnaewele:

• No ka hoʻonohonohoʻana i kahi kānana helu MAC ma kahi mea hoʻopili e hoʻokae i kaʻike pūnaewele wahi i nā mea wale nō i hōʻikeʻia i nā papa inoa i ka papa inoa o nā kuʻuna
• No ka hoʻoholo i ka mea hana o ka mea hana (hapa mua o ka helu wahi) a me ka helu pūnaewele (hapa lua o ka helu wahi), e like me ka lawelawe o ka lawelawe
• No ka hoʻokuʻuʻana i ka waiwai o kahiʻokoʻa'ē aʻe. Hiki ke hoʻohana ponoʻia ka hoʻohanaʻana i ka hao waiwai MAC no ke kākau inoaʻana i kahi pūnaewele puka pūnaewele me ka mea pūnaewele. Eia naʻe, hiki iā ia ke hana i ka manaʻo kolohe, e like me ka hoʻokahuliʻana i ka hiʻohiʻona humuhumuʻana o ka MAC no ka wāwahiʻana i ka pūnaewele

Ka palena o nā Kūlana Kūlana MAC

ʻO ka mea pōʻino, hikiʻole ke nānā i nā helu MAC no nā'ōpili i waho o ke kino o ke kanaka. ʻAʻole hiki ke koho i ka helu MAC o kahi kamepiula mai kona IP pūnaewele wale nō no ka meaʻo kēia mau heluʻelua e puka mai mai nā kumu likeʻole.

ʻO ka hoʻonohonoho pono pūnaewele pono'ī ka mea e hoʻoholo ai i kona helu MAC i ka manawa e hoʻohuiʻia ai ka pūnaewele i ka helu IP.

Eia naʻe, inā pili ka pūnaewele i kahi pūnaewele TCP / IP like, hiki iāʻoe ke hoʻoholo i ka helu MAC ma o kaʻenehana i kapaʻiaʻo ADP (Address Resolution Protocol) , i komo pū me TCP / IP.

Me ka hoʻohanaʻana i ka ARP, ua hoʻohanaʻia kēlā me kēia pūnaewele pūnaewele i ka helu IP a me ka helu MAC no kēlā me kēia mekini i hoʻopuka houʻia. ʻO ka hapanui o nā lolo uila eʻikeʻoe i kēia papa inoa o nā helu kūikawā i hōʻiliʻiliʻia e ARP.

Pehea e hoʻohana ai i ka ARP e Huli i kahi MAC Address

Ma Windows, Linux, a me nā pūnaehana hana'ē aʻe ,ʻo ka laulā laulā kauoha "arp" e hōʻike i kaʻike ma kahi kūlana kūkākūkā MAC i mālamaʻia i loko o ka cache ARP. Eia naʻe, hana wale nō ia i loko o ka hapa liʻiliʻi o nā kamepiula ma kahi pūnaewele wahi (LAN) ,ʻaʻole ma waho o ka pūnaewele.

Nānā: Aia kekahiʻano'ē aʻe i hoʻohanaʻia no ka huliʻana i ka helu MAC o ka kamepiula āu e hoʻohana nei , e pili ana i ka hoʻohanaʻana i ke ipconfig / kauoha (i ka Windows).

Hoʻolālāʻiaʻo ARP e nā luna hoʻoponopono pūnaha aʻaʻole hiki ke hoʻohana pono i nā papapihi a me nā kānaka ma ka pūnaewele.

Akā naʻe, lalo kekahi kumu o ka loaʻaʻana o kahi helu MAC ma o ka helu IP. ʻO ka mea mua, e hoʻomaka i ka pinging i ka mea e makemake aiʻoe e hoʻoponopono i ka MAC no:

Hoʻopaʻa ka papa ping i kahi pilina me kekahi mea'ē aʻe ma ka pūnaewele a pono e hōʻike i kahi hopena e like me kēia:

E hoʻohana i ka papa hana arp o lalo e loaʻa ai kahi papa inoa e hōʻike ana i ka helu MAC o kēlā mea i pinged:

Hiki i nā hualoaʻa ke nānā i kekahi mea e like me kēia, akā me ka nui o nā hanana'ē aʻe:

E huli i ka IP address o ka mea ma ka papa inoa; hōʻike 'ia ka helu MAC ma kahi kokoke. Ma kēia hana, he 192.168.86.45 ka IP IP a me kona helu helu MAC 98-90-96-B9-9D-61 (hiki lākou i ke kahakaha maanei).
