IP address - static vs dynamic, public vs private, shared vs dedicated

Example: 123.45.67.89

Here are some terminologies for IP addresses.

first octet - the first number of the IP (123)
second octet - the second number of the IP (45)
third octet - the third number of the IP (67)
fourth octet - the fourth and last number of the IP (89)

Static means the IP address never changes as long as you stay with the same provider or same server.


Dynamic means the IP address can change from time-to-time.

Public means the IP address can be visited from any computer in the world.

Private means the IP address can only be used by those on the same network.

Shared means other people use your IP address for their connection or websites.


Dedicated
 means no one else uses your IP address for their connection or websites.
due to the shortage of IPv4 addresses, it is no longer possible to buy a single dedicated IP address, then assign it to all of your accounts as a shared IP address without an SSL certificate. All additional IP addresses on your account (which are typically dedicated IPs) need to be associated with a valid SSL certificate.

(We do not provide a dedicated IP address for your personal computer's internet connection or network connection. For that, please contact your internet service provider.)

 

Advanced: The class identifies the range of your IP address and the default subnet mask.

A class - 0 to 127 with default mask of 255.0.0.0
B class - 128 to 191 with default mask of 255.255.0.0
C class - 192 to 223 with default mask of 255.255.255.0
D class - 224 to 247 (not currently used)
E class - 248 to 255 (not currently used)
