Keterbatasan alamat IPv.4 merupakan masalah pada jaringan global atau Internet. Untuk memaksimalkan penggunakan alamat IP yang diberikan oleh Internet Service Provider (ISP) dapat digunakan Network Address Translation atau NAT. NAT membuat jaringan yang menggunakan alamat lokal (private), alamat yang tidak boleh ada dalam tabel routing Internet dan dikhususkan untuk jaringan lokal/intranet, dapat berkomunikasi ke Internet dengan jalan ‘meminjam’ alamat IP Internet yang dialokasikan oleh ISP. Atau dapat juga digunakan untuk koneksi jaringan antar organisasi yang berbeda yang tidak ingin alamat jaringannya diketahui oleh organisasi lain. (more…)

NAT: Local and Global Definitions

Ξ May 23rd, 2006 | → 1 Comments | ∇ NAT, Technology |

Term Definitions

Cisco defines these terms as follows:

  • Inside local address – The IP address assigned to a host on the inside network. This is the address configured as a parameter of the computer’s OS or received via dynamic address allocation protocols such as DHCP. The address is likely not a legitimate IP address assigned by the Network Information Center (NIC) or service provider.
  • Inside global address – A legitimate IP address assigned by the NIC or service provider that represents one or more inside local IP addresses to the outside world.
  • Outside local address – The IP address of an outside host as it appears to the inside network. Not necessarily a legitimate address, it is allocated from an address space routable on the inside.
  • Outside global address – The IP address assigned to a host on the outside network by the host’s owner. The address is allocated from a globally routable address or network space. (more…)
