The ISC DHCP server (dhcpd) was traditionally used to set up a DHCP server in Linux, but the software is reaching end-of-life, and the Internet Systems Consortium is now recommending their own Kea DHCP server or alternatives such as Dnsmasq or udhcpd (as found in Busybox) as a replacement.

I was unaware of this having just used the isc-dhcp-server package to set up a DHCP server in NanoPi R6C router/mini PC earlier this month. But a blog post on Ubuntu informed us dhcpd was going away, and Canonical plans to switch over the Kea DHCP server instead.

The main difference from the user perspective is that Kea relies on JSON configuration files so all your dhcpd files will have to be rewritten.

Other highlights for the Kea DHCP server include:

• Modular component design, extensible with…

When you sign up for internet service from your local Internet Service Provider (ISP), you’re assigned an IP address. Like your home address, this lets your device navigate the internet and help identify a specific device on your network. 

Typically, your ISP provides a dynamic IP address for your connection. However, there are times that a static IP address works better than the usual dynamic IP address. 

How do you determine which IP address to use, and what makes one better than the other? Let’s have a closer look at the difference between static vs. dynamic IP, as well as the strong points for each one.

1. Static IP Is Permanent. Dynamic IP Changes Over Time

First, we need to define what each IP type does to understand its function better….
