Differences Between Static IP and DHCP Assignment
Static IP and DHCP are two very different ways of obtaining an IP address for your computer.
DHCP (Dynamic Host Configuration Protocol) allows your computer to automatically obtain a fully functional IP address from the central RPI DHCP server. Every time you boot up your computer, your operating system retrieves a new IP address. DHCP is the default network configuration for most operating systems. If, however, you need to set up DHCP again, follow the instructions on the various Network Configurations webpages for your specific operating system.
In contrast, static IP is a manual way of obtaining an IP address for your computer, where the IP address is pre-determined and always the same. Web servers and FTP servers are good examples of machines which would require static IP addresses.
Students who wish to run their own server on ResNet would also require a static IP address.
Static IP advantages and disadvantages
There are both advantages and disadvantages to using a static IP address.
| Advantages | Disadvantages |
|---|---|
| Your IP address remains the same so that you can run Internet services that require your IP address to remain the same in order for them to work properly. | You will only be able to effectively use your static IP address from your place of residence. You will be unable to use the web from other places on campus. |
| If, for some reason, the RPI DHCP server is having difficulties handing out IP address, you will still be able to access the web, since your IP is predetermined. | Configuring the network settings on your computer is more difficult for static IP than for DHCP, since DHCP is automatic and static IP is manual. |
