What describes the external IP address that is obtained by a router through a cable or DSL modem?
set the ip configuration to automatic, you have probably define an manual ip adrress which is not in the same range of your dsl modem, also check that you have entered your dsl modem ip address as your gateway in ip configuration page . its usally 192.168.1.1.
You will need to buy a new modem that is designed for your DSL modem. This is due to the fact that the modem is designed to use the dsl signal opposed to the cable modem.
Yes, DSL requires a DSL modem as well as an Ethernet port to your PC or laptop.
The question would be easier to answer if you included the specific model # of the Netgear router you are trying to configure. You can not connect a netgear router or any other router directly to a DSL line unless it also functions as a DSL modem. You can connect a router to a DSL modem which connects to a DSL line.
It is unlikely that you can, as there is no logical reason for an IP address to change every 24 hours, it isn't likely that any modem supports this feature. In addition, most DSL connections would not change the IP address simply because of a power cycle. Because DHCP assigns the IP address to a specific MAC address, you are likely to get the same IP address back after a short power outage.

No, a cable modem connects to a cat5 coax cable and a DSL modem connects to a standard phone line.
Even though modems usually get ip addresses from a DHCP server (dynamic ip address) providers usually bind the modem mac address with a dynamic address. It means that basically you have a fixed ip address. Reseting modems might not necessary mean the modem gets a new ip address. But it happens with certain services.
The comcast modem is a cable modem not a DSL modem so they cant be compared.
The short answer is that you don't. Sure, you can plug a fax modem into a phone line that supports DSL, but it is just using the dial-up capabilities of the line and not the DSL capabilities. A regular modem like that functions like a telephone and transmits in the audible frequency range and not the higher DSL frequencies. With DSL, you'd use a DSL modem (with or without an included router), not a dial-up modem.
You do not need a dial-up modem. However, you will need to either purchase or rent a DSL modem, which works differently from a dial-up modem, and is usually outside the computer.
