Just curious. what would be the advantage of static vs. dynamic?

Dynamic IP addressing is quite simple - kind of plug an play. Very little admin. In a sense it is more secure because what you are assigned can change each time you log on. If you need to know what the address is and you do not want it to change, static is better. For example, if you have a printer with an IP address and it works for weeks and weeks, then it gets power cycled, and now you try printing and it don't work (because the printer has a new address and the PC does not know it).

For me, I choose static because it provides for a very simple qos rule. With that said, it's not exactly static. Static DHCP is very easy to manage and the IP address remains the same.

Does it benefit magic users in the quality sense? If I set up my router to keep the same i.p. for the mac address associated with the mj am I going to get better service? That's a general question(my service is fine). I haven't checked to see my lease ran out on the mj yet so that may change.

I am not sure I understand the question, Does it (static IP) benefit magic users in the quality sense?

QOS will give traffic with certain parameters (that you specify) priority over other traffic (at their expense). Some parameters work well. Some require more router cpu time than others (e.g. L7 filters). If you assign the mj qos rule(s) to an IP you do not want it to change. If you assign it by mac address, which is probably better, the IP can change and the rule is applied to the correct box.

Some people have reported trouble with their routers opening/keeping a connection open (buggy firmware?). A solution reported to work is to move it "outside" into a DMZ (usually by IP address).

Recommendation: If what you have works, don't mess with it.
