Although hosts in IP network are addressed using IP addresses, hardware addresses must be used to actually transport data from one host to another at Layer-2 (EG: Ethernet). Address Resolution Protocol (ARP) provides a mapping between the two different forms of addresses. A router has an ARP table that contains ARP entries. ARP entries consist of IP addresses and corresponding hardware addresses (such as a MAC address). Normally ARP provides a dynamic mapping from an IP address to corresponding hardware address by adding ARP entries automatically as they are discovered, but to increase network security static ARP entries can be created manually. By allowing a router to reply only to those static ARP entries found in the ARP table we restrict access to the router and to the network behind the router to only those IP/Hardware address combinations found in the ARP table. To make a router use only static ARP entries follow the steps listed below.

Ping (singkatan dari Packet Internet Groper) adalah sebuah program utilitas yang digunakan untuk memeriksa konektivitas jaringan berbasis teknologi Transmission Control Protocol/Internet Protocol (TCP/IP). Dengan menggunakan utilitas ini, dapat diuji apakah sebuah komputer terhubung dengan komputer lainnya. Hal ini dilakukan dengan cara mengirim sebuah paket kepada alamat IP yang hendak diujicoba konektivitasnya dan menunggu respons darinya. Nama "ping" datang dari sonar sebuah kapal selam yang sedang aktif, yang sering mengeluarkan bunyi ping ketika menemukan sebuah objek.
