LAN Configuration Field Info Needed to Set Static IP

Ever since I got my MBLD years ago, it disconnects frequently.  I was advised in this community to set my IP Address to Static.  This appears to make sense and may be good for many users.  That said how do I know what to enter for: 1) Netmask; 2) Gateway; and 3) DNS Server???  I assume for IP Address I can just use or something like that that is not already occupied (is that true)?

Thanks for your help.


I found the following link online.

It has all the necesary information on how to set an static IP.

Hope is helpfull.
