Probably not.

Shared IP hosting is the standard, and HTTP 1.1 is mature enough to handle it so browser support is not a concern.

A dedicated IP address is only needed in two conditions:

1) You plan on purchasing an SSL certificate for encryption. These certificates require an account with a dedicated IP. You may use the server's shared SSL certificate without an IP, this only affects users planning on getting their own.

2) You have scripts that require a unique IP address or you have a site that you only want people to view by the IP address (ie http://209.197.236.99).

One additional inconvenience for Microsoft FrontPage users is that it is not possible to publish using the http: method in FrontPage before your domain resolves to your space with a shared IP. Once the domain resolves, this is a non-issue, and you are able to use the ftp: method in the interim. This is a very minor point, mentioned here because it is indeed a "frequently asked question."

Because addresses are getting increasingly scarce, Selltech accounts use a shared IP address. This will work for almost all clients. If you prefer to have a dedicated IP address, please contact us.
