(1) How do I find the IP address of my NIC (network interface card)?

(2) How do I find the IP address of my cable modem (Motorola SB5120)?

Your modem is going to have a Public IP address. This is what is listed under WAN IP for your router, and what IP the internet sees (you can google "what is my IP" and it will list this.

If you are wanting the IP of your Modem to view logs and system status for Motorola modems this is commonly 192.168.100.1

As USAFRet already stated, when you run ipconfig the IPv4 address is the IP of your computer, and FYI the gateway address is your router's IP address

1. Log on to your router config. Its in there
Or...from a commandline - ipconfig /all

2. Log on to your router. Its in there

I did the "ipconfig /all" from a command line, but the result has 6-8 items that all look like IP addresses . . . . .

IPv4 Address
Subnet Mask
Default Gateway
DHCP Server
DNS Servers (2 addresses, they differ by only +1 in the last of 4 fields)
DNS Servers (2 addresses, they differ by only +1 in the last of 4 fields)


. . . . . but none of those names (ASCII strings) tells me which one is the NIC (network interface card) and which the cable modem.


Why = debugging a possible internet security flaw.

IPv4 is the IP address of this particular system.
Default Gateway is what the modem/router presents to the internal devices.

For the Public IP address that you get from your ISP....you need to log onto the router config and look there.

Any idea how to "log onto the router config"?

Thanks.

From a browser...enter the address you get from "Default Gateway"
192.168.x.x...or whatever it actually is.

It will, hopefully, ask you for a username and password.
Do you know the password?

Then I would suspect you entered the wrong IP address for the router.


And just to verify...
The Why is "debugging a possible internet security flaw. "

Not to be funny...but if you can't discover the router login address, or the IP address of the system you are currently on...
what 'debugging' will you be able to do?
