Just remember that the first and last address in any network or subnet can't be assigned to any individual host.
You should now be able to give IP addresses to hosts. It works fine if all computers are on a single network. However, your computers are on three separate physical networks. Instead of requesting more address blocks for each network, you divide your network into subnets that enable you to use one block of addresses on multiple physical networks. In this case, you divide your network into four subnets by using a subnet mask that makes the network address larger and the possible range of host addresses smaller.
In other words, you are 'borrowing' some of the bits used for the host address, and using them for the network portion of the address. The subnet mask It works because in binary notation, The first two digits of the last octet become network addresses, so you get the additional networks 0 , 64 , and Some administrators will only use two of the subnetworks using For more information on this topic, see RFC In these four networks, the last six binary digits can be used for host addresses.
Using a subnet mask of These four networks would have as valid host addresses:. Remember, again, that binary host addresses with all ones or all zeros are invalid, so you can't use addresses with the last octet of 0, 63, 64, , , , , or You can see how it works by looking at two host addresses, If you used the default Class C subnet mask of However, if you use the subnet mask of The result of this comparison tells the computer whether the destination is a local host or a remote host.
If the result of this process determines the destination to be a local host, then the computer will send the packet on the local subnet. It's then the responsibility of the router to forward the packet to the correct subnet.
Incorrect Subnet Mask: If a network uses a subnet mask other than the default mask for its address class, and a client is still configured with the default subnet mask for the address class, communication will fail to some nearby networks but not to distant ones. As an example, if you create four subnets such as in the subnetting example but use the incorrect subnet mask of In this situation, packets destined for hosts on different physical networks that are part of the same Class C address won't be sent to a default gateway for delivery.
A common symptom of this issue is when a computer can communicate with hosts that are on its local network and can talk to all remote networks except those networks that are nearby and have the same class A, B, or C address. When a proxy server sits between a client and the Office data centers, media might be forced over TCP instead of UDP, which would impact media quality.

If your networking and security policies require Microsoft or Office traffic to flow through a proxy server, make sure that the above requirements are already met before deploying Teams into production.
