Anatomy of an IP address<\/span><\/strong><\/p>\n

\"\"<\/a><\/p>\n

IPv4 addresses is made of 32 bits divided into 4 octets (each octet s 8 bits).<\/p>\n

An IP address can be divided into 2 portions: the network portion and the host portion<\/strong><\/em>. The network portion determines the bits within the IP address that belongs to the network (or subnetwork), while the host portion are the hosts within the subnet.<\/p>\n

Network portion is identified by the subnet mask. In the example given, the subnet mask is given (\/24) and 24 bits are the network portion.<\/p>\n

The host portion is 8 bits – this means that the subnet can give and IP address and have up to ((2^8)-2) = 254 different devices within the subnet.<\/p>\n

 <\/p>\n

 <\/p>\n

\"\"<\/a><\/p>\n

 <\/p>\n

In this next example, 172.16.1.0\/16, you see that the network portion is smaller (16 bits) while the host portion is bigger (16 bits). In this particular subnet, it can hold up to ((2^16)-2) = 65534 different devices.<\/p>\n

So, the bigger the host portion, the more unique addresses it has and the more different devices it can have.<\/p>\n

 <\/p>\n

 <\/p>\n

 <\/p>\n

 <\/p>\n

Given these IP addresses, can you identify the network portion and the host portion? Give it a try.<\/p>\n
