Is Mac and IP Address Binding the same as reserving the IP address? the router in question is an Asus RT-AX3000.
Not familiar with that specific router, but that phrasing sounds exactly like what you're looking for (always handing out--reserving--the same DHCP IP address to a device based on its MAC).

Is it in the DHCP section of the config? If so, @bertabcd1234 is probably correct. But, from the name, it sounds more like the ability to create a static ARP entry.

MAC and IP binding does usually have more to do with ARP but who knows... here's what I found in the Asus documentation. If this screen looks like yours, this should do it.
So, the IP-to-MAC binding is more of a security feature, while the DHCP reservation is more of a ease of use or convenience feature.

Well, this question came more because of poking around and remembering past discussions. I honestly thought I had IP reserved the hub addresses on the router in the past. Here is a screenshot of the settings I'm looking at in the router.
So I guess the question would have now, from a security standpoint would it be a good idea to turn this on for my hubs (and phones since I use them for presence)? I assume by doing so would it affect the day-to-day other than keeping them from possibly having another address assigned at some point?
Should be no problem. It's a bit more secure than plain reservation and won't hurt anything and static IP's are preferred.
I ran an Asus router for years, like it so much I flashed Asus on my netgear router.
If you want to see some neat info get the Net Analyzer app by Jiri Techet. You'll be able to see everything on your network and do wifi scans to check for neighbors' interference
