At the moment, we have 27 single sites in IIS6, all with their own urls, all with the same subdomain, e.g.

etc., etc.

To further complicate things, there is 1 wild card certificate which deals with the subdomain * and is assigned to each website.

All these websites run under the same codebase.

We want to consolidate all these websites into 1 website.

Are there any issues with having a large number of host headers running under 1 IIS6 site or is there a better way of configuring the site?

If you're asking if you can have 27 virtual hosts on 1 IIS6 website, the answer is 'absolutely'. Virtual hosts scale to hundreds.

There's really no issue at all. Using host headers is more resource friendly than using separate IP addresses since the WWW service needs to manage individual endpoints for separate IP addresses.
