Subnet Masana Definition a me nā hōʻailona
ʻO ka mask subnet ka inoa o IP -like e like me ka nui o ke subnetwork i pili i kahi kamepiula a iʻole kekahi mea'ē aʻe. He 32-bit ka helu nāna eʻoki i ka IP IP i loko o kona mau meaʻelua: ka helu pūnaewele a me ka helu wahi noho.
ʻO ka mask subnet (a kapaʻiaʻo netmask), laila, ua hoʻohālikelikeʻia e like me kēia:
Hoʻokumuʻia ka mask subnet e ke kauʻana i nā kikowaena pūnaewele a 1s a me nā huina host i ka 0s. Hiki i nā pūnaewele hoʻonohonoho pūnaeweleʻelua mau helu inoa i hikiʻole ke hāʻawiʻia i nā pūʻali, aʻo nā mea i loaʻa no ka helu pūnaewele a me 255 no ka wālepa hoʻolaha.
Nā Subnet Mask Nā Hōʻailona
Eia nā netmasks i hoʻohanaʻia no ka Class A (16-bit), ke Class B (16-bit), a me ka papa C (24 mau bit):
- Hākoʻo nā papahana Akahi i ka 16,777,216 pūʻali a loaʻa iā lākou ka masque subnet of 255.0.0.0.
- Loaʻa nā papahana B Class i kahi mask subnet o 255.255.0.0 a hiki wale ke loaʻa i 65,534 nā polokalamu IP.
- ʻO ka hapanui o nā papahana home he papa C, i kuhikuhiʻia e kahi mask ma ka lika 255.255.255.0. Hiki i kēia nui o ka pūnaewele ke komo i 256 Pūnaewele IP, piha ka lumi no kekahi hale noho aʻoihana paha.
E noʻonoʻo i ka helu IP IP 128.71.216.118. Inā manaʻo mākou he kūlana B Class ia, nā helu heluʻelua (128.71) e ho'ākāka i ka helu pūnaewele B Class i ka manawa o nāʻelua hope loa (216.118) e hoʻomaopopo i ka helu wahi noho.
Eʻike i nā mea hou e pili ana i nā masks subnet i loko o kā mākou Subnet Masks a me Subtiting tutorial.
