What's the fastest and or easiest way to find out what ip address is being assigned by the ISP? I'm prettty sure my ISP uses DHCP.

Are you referring to your "public" IP address? If so, try going to: www.whatismyip.com.

OR - from a command prompt window, type ipconfig /all Rule #1 Good computers don't go down. Rule #2 There is no such thing as a good computer.

ipconfig /all would be the fastest way to find out that information.... if you want a new ip address: ipconfig /release ipconfig /renew

People, please read the question properly! The question refers to the IP assigned by the ISP. Being behind a router, or some DSL modems, ipconfig would give the IP address on the local network, NOT the one assigned by the ISP. As Daniel suggested, go to www.whatismyip.com. Please let us know if you found someone's advice to be helpful.

Most systems using DHCP will return an ipconfig/renew with the same address you already have. There is a hardware level code (MAC address) in the network card that is used to match to the IP address when you lease a connection. Typically a lease is for 1-3 days. If you do a renew a new lease for another time period is matched to the MAC address to the IP address. Typically when troubleshooting a connection problem the release/renew is used to see that the DHCP server supplies an address. The one thing that using "new at this" suggests is that if your ISP uses dhcp the display will refresh with an IP address string. Note the example below. C:\>ipconfig /all Windows 2000 IP Configuration Host Name . . . . . . . . . . . . : XXXXX Primary DNS Suffix . . . . . . . : XXXXXX Node Type . . . . . . . . . . . . : Broadcast IP Routing Enabled. . . . . . . . : No WINS Proxy Enabled. . . . . . . . : No DNS Suffix Search List. . . . . . : XXXXXX Ethernet adapter Local Area Connection: Connection-specific DNS Suffix . : Description . . . . . . . . . . . : Intel(R) PRO/100 S Desktop Adapter Physical Address. . . . . . . . . : 00-XX-XX-XX-XX-XX DHCP Enabled. . . . . . . . . . . : Yes Autoconfiguration Enabled . . . . : Yes IP Address. . . . . . . . . . . . : 192.XXX.XXX.XXX Subnet Mask . . . . . . . . . . . : 255.255.255.0 Default Gateway . . . . . . . . . : 192.XXX.XXX.XXX DHCP Server . . . . . . . . . . . : 192.XXX.XXX.XXX DNS Servers . . . . . . . . . . . : 192.XXX.XXX.XXX Lease Obtained. . . . . . . . . . : Monday, August 22, 2005 6:37:15 PM Lease Expires . . . . . . . . . . : Tuesday, August 23, 2005 3:33:07 PM C:\> This is a typical ipconfig request result.

note Richard that you are listing local not ISP provide ip. I agree with you Sci-Guy
