255.255.255.0 Subnet Mask

Mauthenga a subnet 255.255.255.0 ndi a subnet mask omwe amagwiritsidwa ntchito pa makompyuta ogwirizana ndi intaneti Internet Protocol (IPv4) . Kuwonjezera pa kugwiritsira ntchito pa makina oyendetsa kunyumba , mungathe kukumana ndi chigoba ichi pa mayesero ovomerezeka ogwira ntchito monga Network CCNA .

Mabanki amagwiritsa ntchito mipanda yeniyeni, akugawaniza ma adresse a IP mu timagulu ting'onoang'ono. Chizoloŵezichi chimachepetsa chisokonezo cha intaneti ndikulowetsamo mwayi wofikira pazomwe zili pansi pake.

Chigoba cha subnet chimazindikiritsa munthu wogonjera.

255.255.255.0 ndi subnetting

Mapulogalamu achikale amagwiritsidwa ntchito ndi otchedwa ma intaneti omwe amagawira ma Adresse a IP ku imodzi mwa makalasi asanu (Kalasi A / B / C / D / E) malinga ndi kufunika kwa nambala ya adiresi ya IP.

Tsamba la subnet 255.255.255.0 limasinthidwa ku mtengo wamphindi wa 32-bit:

• 11111111 11111111 11111111 00000000

Nambala 0 za chigoba ichi zimayambira ma pulogalamu 8 a ma subnet-8 kapena ma 256 pakadali pano. Nambala yochuluka ya subnetworks yaying'ono imatha kufotokozedwa posintha maski monga momwe tawonetsera mu tebulo ili m'munsimu.

Kukonzekera kosayenera kwa subnet mask (kotchedwanso netmask ) kumayambitsa mitundu yolepheretsa kugwirizanitsa .

Mabanki ndi CIDR

Mu chikhalidwe chodziwika bwino, maadiresi ambiri osagwiritsidwa ntchito a IP adasokonekera chifukwa opereka ma intaneti ndi makampani akuluakulu amasungidwa ma adiresi omwe sangathe kugawana nawo.

Ambiri mwa intaneti adasandulika kukhala a IP osagwirizana kwambiri kuti athetsere ndondomeko zogawidwa komanso kuthana ndi kufunika kwa IPv4 ma intaneti m'zaka za m'ma 1990.

Mitundu yopanda malire imatembenuza machitidwe achikhalidwe a subnet kufupi ndi zolemba zowerengeka zochokera ku chiwerengero cha ma chiwerengero chimodzi mu chigoba.

Kusakanikirana kwapakati pazomwe amalembera maulamuliro amodzi akulemba adiresi ya IP komanso yogwirizanitsa maskiti ake mwa mawonekedwe:

XXX.xxx.xxx.xxx/n

Pano, n imaimira nambala pakati pa 1 ndi 31 yomwe ili nambala ya bits 1 mu maski.

CIDR imathandizira mapulogalamu osungira apadera a IP omwe ali nawo ndi masayiti a masikiti ndi ma nambala a makina a IP osagwirizana ndi chikhalidwe chawo. Othandizira omwe amathandiza CIDR kuzindikira mapulogalamuwa ngati njira zapadera, ngakhale kuti angayimire gulu lazinthu zosiyanasiyana.

Makomiti a Network

Bungwe la InterNIC limene limapereka mayina a mayina a intaneti likugawa ma adresse a IP ku makalasi. Zambiri mwa izi ndizigawo A, B, ndi C. Mabungwe a C Class C onse amagwiritsa ntchito masanjidwe osasintha a 255.255.255.0.

Kugwiritsa ntchito 255.255.255.0 monga IP Address

Ngakhale kuti amawonetsedwa ngati mawonekedwe a adiresi ya IP, zipangizo zamakono zingagwiritse ntchito 255.255.255.0 monga mask osati monga adiresi ya IP. Kuyesera kugwiritsa ntchito chiwerengero ichi (kapena chiwerengero chilichonse cha IP chomwe chimayambira ndi 255) monga adresi ya chipangizo chimapangitsa pulogalamu ya IP kusokonekera chifukwa cha kutanthauzira kwa mndandanda wa mapulogalamu pa IP.
