For example, if an Internet Service Provider (ISP) is assigned a “/16”, they receive around 64,000 IPv4 addresses. A “/26” network provides 64 IPv4 addresses. The lower the number after the oblique, the more addresses contained in that “block”.

What does a 16 network mean?

The `/16′ means that the first 16 binary digits is the network address, in other words, the `1.2. ‘ part is the the network (remember: each digit represents 8 binary digits). This means any IP address beginning with `1.2. … 0.0/8’ is a big network containing any address from 10.0. 0.0 to 10.255.
