Abstract. This paper aims to assess how the Dhcp service that is essential to a protocol that connects a computer to a network to get dynamically (ie, without specific intervention) your settings (mainly its network configuration). You only have to tell the computer to find yourself an IP address through DHCP. The main objective is to simplify network administration. Resumo. Neste artigo visa verificar como funciona o serviço de Dhcp que é um protocolo indispensável para

use a port number between 1024 and 65535. Every computer that you want to play the game on should be given a different port number if they are all behind the same firewall. To return to the automatic mode, remove the port number from the "port number" edit box. If you specify a port for Red Alert 2TM to use then you will have to manually configure your firewall with static IP and port forwarding to route packets to the correct computer. Each firewalls configuration method…

to the server. All cables have been tested and are working and all devices have IP addressing. However, the user cannot ping the server. What is causing the problem? • The router interface does not have a default gateway. • The switch does not have an IP address and default gateway. • The workstation and server are on different logical networks. • The workstation does not know the MAC address of the switch. Q.3. Which part of an IP address identifies a specific device…
