Day 14: Static and Dynamic Addressing

Hosts in our LAN can be assigned an IP address in one of two ways:
  • Manual configuration: we can enter a static IP address, subnet mask, and gateway on hosts in our network. These static addresses remain the same for these devices unless we manually change'em.
  • Dynamic configuration: we can configure a DHCP server (as discussed on day 15) to dynamically assign addresses to computers on your network. We can specify the address range, client lease and other parameters on the DHCP server. You also need to configure clients to request addressing information from the DHCP server. 
Remember the ip helper-address command used to forward DHCP requests. 

Use the ipconfig /release and ipconfig /renew commands to refresh.
