What is the range of Class An IP addresses? I believe that many inexperienced people are at a loss about this, so this article summarizes the causes and solutions of the problem. Through this article, I hope you can solve this problem.

The range of Class An IP addresses is 0.0.0.0 to 127.255.255.255.

The first byte of the class An address is the network address and the other three bytes are the host address. In addition, the highest bit of the first byte is fixed at 0.

It should be emphasized here that the numbers 0 and 127 are not the IP addresses of the host, and the number 127 is reserved for the internal echo function, while the number 0 indicates that the address is a local host and cannot be transmitted, but 0 and 127 do belong to class An addresses, so there are only 126 addresses for class An addresses at most.

Private and reserved addresses in Class An addresses:

10.0.0.0 to 10.255.255.255 are private addresses (so-called private addresses are addresses that are not used on the Internet but are used in the local area network).

127.0.0.0 to 127.255.255.255 are reserved addresses for circular testing.

0.0.0.0 to 0.255.255.255 are also reserved addresses and are used to represent all IP addresses.

The default subnet mask for class An addresses is 255.0.0.0
