How to Choose IP Range

Networked computers connect to a router using a range of IP addresses. Choose your range with these tips.


  • Step 1: Know the ranges Learn the three IP ranges: to, to, and to
  • TIP: Don't use the 172.16 range, as it is hardly ever used and could cause problems along the way.
  • Step 2: Identify network size Decide how large and complex your network is. A large network is more than 200 computers, and is likely to grow and branch off into multiple networks. A small network is fewer than 200 computers.
  • Step 3: Choose the small range Choose the 192.168 range for small networks. This option will give you 256 IP Addresses.
  • Step 4: Use 10 for the large range Use the range for large networks.
  • Step 5: Avoid common ranges Avoid using common ranges such as to, 192.168.000 to, and to A common range makes it easier for a hacker to break into the network.
  • FACT: Because of the number of digits in IP addresses, there are around four billion individual IP address possibilities, and they are rapidly running out.
