In continuation of our articles focused on the basics of IP addresses we look at dynamic and static IP addresses. All IP addresses are classified as either dynamic or static. Dynamic and static IP addresses can also be classified as either public or private but we will save that for another article.
The format of a dynamic IP address is the same as a static IP address and not distinguishable by just looking at the address. For private dynamic and static IP addresses the address will typically begin with either 10. or 192.168.
In short, using a dynamic IP address is likely the best option unless you have a particular use case or are maintaining many devices across a business network. Understanding the differences is important to knowing the basics of networking. Stay tuned for more articles on networking and IP basics.
What is a Dynamic IP Address?
A dynamic IP address is one that is assigned as a device connects to a network and may be different each time the device connects. The dynamic IP address is assigned and managed by the Dynamic Host Configuration Protocol (DHCP) server, which is usually a function of the router.The format of a dynamic IP address is the same as a static IP address and not distinguishable by just looking at the address. For private dynamic and static IP addresses the address will typically begin with either 10. or 192.168.
Reasons To Have a Static IP Address
The are several reasons why network administrators and home users might want to use static IP addresses:- Ease of access: Static IP addresses are helpful when needing to access a server or specific device such as a printer, or network storage.
- Required by service: Some services, such as VPNs or servers, may require a static IP address to be configured. For example, this website has a static IP address that is configured in the DNS settings to resolve IPSearch.io to a specific static IP.
- Security: Using static IP addresses makes it easier to track each device on the network and research historical events in log files
Reasons To Have a Dynamic IP Address
The primary reasons to using dynamic IP addresses is that the device doesn't act as a server and it is easier to connect and maintain a device . For example, you can connect your phone or laptop to a network without having to enter IP address configuration details.In short, using a dynamic IP address is likely the best option unless you have a particular use case or are maintaining many devices across a business network.
