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 in Windows 9x/ME
Start >> Run >> type in winipcfg
For Windows XP/2000/NT users, run a command line interface (CLI):
Start >> Run >> type in 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
