As IP subnets have grown, administrators have looked for ways to use their address space more efficiently. This page introduces a technique called VLSM. With VLSM, a network administrator can use a long mask on networks with few hosts, and a short mask on subnets with many hosts. In order to implement VLSM, a network…
Network administrators must anticipate and manage the physical growth of networks. This may require them to buy or lease another floor of a building for new network equipment such as racks, patch panels, switches, and routers. Network designers must choose address schemes that allow for growth. Variable-length subnet mask (VLSM) is used to create efficient…
Merhaba arkadaslar, sizlere bu unitede gorecegimiz bazi konulardan bahsedip bir on giris yapmak istiyorum. Tahmin edildigi uzere network yoneticileri bir network kurarken o networkun ileriki zamanlarda fiziksel olarak buyuyebilecek olmasi ihtimalini daima goz onunde bulundurmalari ve buna gore yonetim politikalarini ve alinacak cihazlari belirlemeleri gerekir. Ayni zamanda networku dizayn eden kisilerin de kullanacaklari adres semalari…
NAT(translations) tercümeleri bir çok çeşit amaç için kullanılabilir. İster Dinamik ister statik(durgun) olarak ayarlanabilir. Static NAT local ve global adresleri birebir eşleyebilmek için dizayn edilmiştir. Biliyorsunuz ki NAT kullanıldıgı zaman internetten birisi NAT’ın altındaki hostların ip adreslerini göremez. Ancak Statik NAT bize öyle bir imkan sunuyor ki, internetten ip sine erişilmesini istedigimiz bir hostu bu…
