Customers often ask us if they can use an IP address in an SSL certificate instead of a fully qualified domain name. The short answer is yes, but we only recommend it if you cannot use a domain name.
You must consider specific stipulations, conditions, and limitations if you need an IP in your cert.
Domain Validated (DV) and Organization Validated (OV) certificates only (EV certs cannot have an IP address)
You must prove that you "own" or control the IP by hosting a .txt file containing a generated random string token at a predetermined location on your website. We will provide you with this token and instructions after you submit your IP SSL order. Before placing an IP certificate order, you'll want to review the steps required to prove IP ownership by the HTTPS File-based Token DCV method.
Which SSL certificate products will support a public IP address?
Can I add an IP Address as a SAN mixed with other IP Addresses or FQDNs?
Yes! You can add a SAN for an IP Address to any non-EV Multi-domain Certificate. The SANs must meet the same requirements and restrictions mentioned above. See more FAQs about using an IP address in SSL certificates.
If you absolutely cannot prove you control the IP
If you cannot prove your organization has been assigned the IP by placing a .txt file on your web server, there is a workaround, but it's not recommended as a first choice. The vetting team can attempt to call the Point of Contact (POC) listed on the WHOIS for your IP address to confirm you have permission to use the IP. Please understand that while the vetting team can attempt to place a call to the POC, there's no guarantee the POC take the call or call them back.
To see the underlying WHOIS information for your IP, you can use the following approved links for official IP contacts and assignments.
Dedicated IP addresses used to be a necessity if you wanted to install an SSL certificate on your site. But, with changing technology it's no longer a requirement. Typically, if you are using a dedicated IP address this will be because you're using a dedicated web server.
In IP SSL mode, a certificate for a specific DNS hostname is mapped to a dedicated virtual IP Address. However, for IP SSL to work, dedicated and unique addresses must use IP sockets, represented by IP address and port number combinations, not just the IP address.
For an SSL certificate to be valid, domains need to obtain it from a certificate authority (CA). A CA is an outside organization, a trusted third party, that generates and gives out SSL certificates. The CA will also digitally sign the certificate with their own private key, allowing client devices to verify it.
The short answer is yes, but we only recommend it if you cannot use a domain name. You must consider specific stipulations, conditions, and limitations if you need an IP in your cert.
An SSL proxy is anonymous – a proxy will hide your IP, but the added safety of the SSL layer increases your anonymity, as it reduces the information available about your connection request.
If you need to deliver content to browsers that don't support SNI, you can use the Dedicated IP Custom SSL feature. For this feature the Amazon content delivery network allocates dedicated IP addresses to serve your SSL content at each Edge location.
The IPsec protocol suite operates at the network layer of the OSI model. It runs directly on top of IP (the Internet Protocol), which is responsible for routing data packets. Meanwhile, SSL operates at the application layer of the OSI model.It encrypts HTTP traffic instead of directly encrypting IP packets.
An SSL certificate is a file installed on a website's origin server. It's simply a data file containing the public key and the identity of the website owner, along with other information. Without an SSL certificate, a website's traffic can't be encrypted with TLS.
The most common cause of a "certificate not trusted" error is that the certificate installation was not properly completed on the server (or servers) hosting the site. Use our SSL Certificate tester to check for this issue. In the tester, an incomplete installation shows one certificate file and a broken red chain.
What is an SSL certificate error? An SSL certificate error occurs when a web browser can't verify the SSL certificate installed on a site. Rather than connect users to your website, the browser will display an error message, warning users that the site may be insecure.
With SSL, authentication is performed by an exchange of certificates, which are blocks of data in a format described in ITU-T standard X. 509. The X. 509 certificates are issued, and digitally signed by an external authority known as a certificate authority.
Website owners need to obtain an SSL certificate from a certificate authority, and then install it on their web server (often a web host can handle this process). A certificate authority is an outside party who can confirm that the website owner is who they say they are. They keep a copy of the certificates they issue.
A: If you run a website that relies on high integrity and hosting reliability, it is better to make use of a dedicated IP address. Some web applications may also require a dedicated IP address to work correctly.
An SSL certificate can't be issued for Reserved IP addresses (RFC 1918 and RFC 4193 range)/ private IP addresses (IPv4, IPv6), Intranet for Internal Server Name, local server name with a non-public domain name suffix. Extended Validated (EV) SSL are not permitted to be issued for an IP address.
Almost all hosting providers offer SSL certificates, so you may not have to deal with a third-party organization if you don't want to. However, if you're unsure if your plan comes with this security feature, talk to your hosting provider to see if you can get one for free or purchase one.
