About Entering Addresses
When you type IPv4 addresses in the Quick Setup Wizard or dialog boxes, type the digits and decimals in the correct sequence. Do not use the TAB key, arrow keys, spacebar, or mouse to put your cursor after the decimals.
For example, if you type the IP address 172.16.1.10, do not type a space after you type 16. Do not try to put your cursor after the subsequent decimal to type 1. Type a decimal directly after 16, and then type 1.10. Press the slash (/) key to move to the netmask.
When you type IPv6 addresses in a text box, simply type the IP address with the colons to separate each group of numbers in the address. To shorten an IP address, you can remove leading zeros in each group of numbers and you can use a double colon (::) to replace adjacent groups of zeros in the address.
