Do I Need Dedicated IP Address to Install SSL/TLS Certificate On Website?
Possibility to Comply With Google Policy of Having an SSL/TLS Certificate Installed Without Dedicated IP Address
On the other hand, SSL installation is another question. Though it may look quite technical for new users, the overall process is relatively easy. However, one question still lingers around, though it’s not often asked always sometimes it does popups – Do you need a dedicated IP address if you’ve to install an SSL/TLS certificate.
A dedicated IP address is not mandatory to install an SSL/TLS Certificate.
Now, let’s look into the bigger picture, why some hosts still suggest that you must have a dedicated IP address before allowing you to install an SSL/TLS certificate.
But before we get into details, let’s understand what’s dedicated IP address.
What’s IP Address
It’s similar to our home address, which is unique for everyone –every device has its unique IP address. For example, if you’re using a smartphone or computer, each will represent an IP address for that device, and in the same way, your website also has the unique IP address that tells the server where the website is hosted.
Furthermore, when it comes to the website, there are two different types of IP addresses – shared IP address & dedicated IP address.
- A shared IP address means multiple users are allowed to host their website on the same server, or even your multiple websites are stored on the same server.
- A dedicated IP address means each IP address is specifically dedicated to one particular website.
Also, people go with shared IP addresses due to its cost-effectiveness. But in some scenarios like a business website, where a massive chunk of data is dealt with daily basis, a dedicated IP address is also seen. And this is also one of the reasons why hosting companies tell the user to go with a dedicated IP address instead of a shared one.
Protection From Online Threats & Phishing Attacks
EV SSL/TLS certificate is the certificate that isn’t easy to obtain. An applicant has to go through a very stringent verification process that verifies organization details, and even phone call verification is done, which makes it impossible for cyber crooks to obtain it. Other than that, it also provides visual indicators such as the name of the organization on clicking certificate details, which makes it easy for users to spot whether they’re on the right website or not.
Also, the research was done by Georgia Tech’s Cyber Forensics Innovation (CyFI) Lab on Extended Validated SSL/TLS Certificate. It concluded that 99.99% of the time, it’s not possible for cybercriminals to get EV SSL/TLS certificate by researching around 2.6 million domain names earlier from 2010.
Which One to Consider – Dedicated or Shared IP Address for an SSL/TLS Certificate
If you’ve asked this question some years back, the straight answer would’ve been a dedicated IP address without being questioned. But, thanks to the SNI (Server Name Indication) technology. Now, there’s the possibility to host more than one website on a single IP address.
In today’s date, usually, all the servers come along with the SNI technology, which makes it possible to host multiple SSL/TLS certificates for websites. So, if you’re out there who’s looking to host multiple SSL/TLS certificates for numerous websites on a single IP address, SNI will help to create a virtual host environment for the additional SSL equipped websites.

Multi-Domain (SAN) SSL/TLS Certificate a Breeze
Though, be careful that you haven’t already purchased any SSL/TLS certificate because the option of Multi-Domain SSL/TLS certificate will only be useful if you haven’t installed SSL/TLS certificate on any of the website. If you have, then you won’t be able to install SSL on that particular website or websites.
