Guide To Running Wildcard SSL On Single IP Address

March 11, 2013 | By  

While the purpose of having a secure environment to work with is the prime agenda when using secure sockets layer or Wildcard SSL, sometimes the host may also face issues with regards to the ip address, search engine ranking and more. Certificate authorities are the people behind who issue the cert and they constantly enhance their service quality which allows companies to make better use of the SSL certificate. The encryption module is an important addition for websites which acquire personal data, financial information, or transact money for products or service. It helps them make sure that such important customer data don’t fall into wrong hands. The encryption can be done in 128 bit and 256 bit based on the product as well as the plan that you opt for.

To provide increased security, browsers recognize only CA signed wildcard ssl digital certificates to be authentic. For this purpose, private keys are issued and distributed widely. Only when the authentication process is completed, users will be notified of the website’s legitimacy and they can continue to complete the transaction. In recent times, the issuing authority have come with unique ways to solve the ip address issue. As Wildcard SSL is issued to multiple domain extensions and sub-domains, they required long authentication process. To help solve them, the companies will introduce a combination of Server Name Indication SNI which will allow it to run on single IP address and there is no need to update the DNS.

Using Wildcard SSL With Single IP Address

With so many websites running mostly on Ipv4 protocol, it is now completely full up to the brim but the new update will open a whole new world of Ipv6 protocol based security solutions. The problem runs with the fact that each individual SSL requires a separate dedicated IP address. Of late, Ipv4 has been running out and there is dire shortage of dedicated solutions from the said protocol. It also drastically constrains the concept of reselling certificates to new companies which in turn not only affects Certificate Authority revenue issues but also limits users from buying certs at affordable price range.

The new development found in wildcard ssl is based on the Server Name Indication extension or SNI yet this technology is not widely adopted by all browsers. Experts suggest cloud based validation for browsers without support will do the trick.

Comodo has been the pioneers of adopting new technology and is one of the leading providers of Wildcard SSL certificate. Expert assistance and all types of certificate solutions is assured at Comodo.
