Note on Dynamic DNS:
I want to make special note of Dynamic DNS(DDNS). A lot of newer routers do have provisions to utilize this. The purpose of DDNS is this. every computer on the internet is given a unique number called an IP address. This number is not user friendly and often can "Dynamically" change. for this reason we use a DDNS provider so that we have a non changing means of locating a resource on the internet. It also provides a nice user friendly name. Your IP address is pointed to this name so if you want to connect to your home you would enter the friendly name. if your router supports DDNS it will automatically refresh or update the pointer if your ip address changes. This does happen quite often for some internet provider and others not as much. But it does happen and having to go to each and every device to change the number you entered is just crazy. so this makes it all happen automatically. You will have to read up on how to do this for your router and for the DDNS provider you would like to use.
Dynamically Assigned Static IP:
This is the Dynamic Host Configuration Protocol(DHCP) setup page on my router. This is where your router issues those IP addresses to your devices/computers. what we are interested in is either going to be called Static Assignment or something like what my red arrow is pointing at.
We Want to make note of the Start Range and Stop Range. we want to number we are going to set fall inside that range.
This is the page to make that IP address a dynamically assigned static IP address. Meaning that it is still handed to your computer but the number will never change there for making it static if you will but the right term here is never changing.
A: the IP address we want to EG computer to have. remember we want it to fall inside of that range as mentioned above.
B: the MAC address of the computer that is running EG. We got that number from the CLI window with the ipconfig command. This number in the CLI windows is separated my a - some routers you have to enter a : some the - and some a space and some nothing at all just push all the numbers together. (numbers: this is a hex decimal representation of a number, because the number is so long it would be crazy to have to key the whole thing out. put it to you this way. there are 281,474,976,710,656 different possible MAC address combinations, and an IP address has 4,294,967,296 combinations, and we have done run out of public IP addresses. so the new IPV6 has 340,282,366,920,938,000,000,000,000,000,000,000,000 possible combinations and also uses the hex pairings like the MAC address. but this is a whole nothing conversation.
C: Some name you would like to give to this assignment
D: Enable It
E: Add it
and remember to save
