Understand the importance of your IP Address
What is an IP Address?
For those of you that are not quite sure what an IP Address actually is here is a brief explanation.
Simply an IP Address is a complex string of numbers assigned to a device on a network that allows the devices to communicate with each other. You may have seen them before here is an example of an IP Address 172.31.255.255.
Each website has an IP Address but users would have great difficulty remembering an IP Address so the Domain Name was created like mydomain.com and this is ‘attached’ to the IP Address. There is a lot more to IP Addresses than this however that is sufficient for this article.
You can find out your IP Address at the following websites
Hosting Your Website
Where and how you host your website is important.
If you have one server, it has one IP address. If you dont have any other domain names/hosts on that server you have complete control over that IP Address.
If you share your server with other websites then all those websites have the same IP Address. This is called shared hosting. Now if one of those websites was infected for example with a mailbot and it started sending our spam, it will most likely end up on an Email Blacklist. If this happens the IP Address is blacklisted and bingo so is your website because you are sharing the same IP Address.
Using a unique IP Address
It is clear then that you should use a dedicated IP Address. However the costs of having a dedicated server for one website normally is out of the question for most WordPress owners.
Choosing the right hosting company means they can assign you a dedicated IP Address even though it maybe on a shared server.
Ensure you have a dedicated IP Address.
