# Setting up your ips.ini file

The ips.ini will determine which IP addresses have access to reserved slots. IP stands for Internet Protocol. IP addresses are a series of 4 numbers, with each number in the range 0 to 255.

What's my IP address?

If you do not know your IP address, you can get it by running

Start >> Run >> winipcfg in Windows 9x.

For windows2000/NT users, run a command line interface (CLI):

Start >> Run >> cmd and enter "ipconfig" at the command prompt.

Linux users get their IP by entering on the command line:

hostname –i or, even better, ifconfig.

How do I enter the IP addresses in my ips.ini file?

Single IP numbers can be entered as follows (no port numbers are required):

129.49.231.126

172.54.512.7

If you use subnets (common in Ethernet Local Area Networks) you can specify your subnet mask (kind of like and IP inside an IP)

129.49.231.126/255.255.255.0

To cover all IPs between 168.23.21.0 and 168.23.21.255, simply set the last digit to 0

168.23.21.0

To cover all IPs starting with 168.23, simply add:

168.23.0.0
