Hi, so i am developing a website for my client’s internal use, and they can’t have a domain name due to their company rules. So my users will just type in the ip address to the address bar. Some of their web features needs a ssl certification in order to run, such as geolocation.
How can i get SSL certification on IP Address, so it could go like this for example: https://123.45.67.89
Thanks.

Digicert can issue you an ssl certificate for your a public ip address.
You or your client may want to consider using a VPN along with internal DNS to access this app.
You should still use TLS for your app, of course.
Most common use cases call for a domain when using SSL. It is possible however to create an SSL certificate for an IP address. Unfortunately the free LetsEncrypt CA does not support this which leaves you with two options:
-
Create a self-signed ssl certificate. This has the benefit of being free and fairly easy to set up but will result in a security warning in most browsers since they look for a trusted authority to have issued the certificate. If you are creating this for internal use this may be the best option.
-
Purchase an SSL certificate from a provider. For this I’d recommend reaching out to a few providers to find one that will support issuing a certificate for your public IP address.
