The site resides on my server, however, their IT support company manages the domain and their email configuration.
So far, so good.
However, it transpires that as standard practice, they (the IT bods) use wildcard subdomains. So, 123.clientdomain.com, abc.clientdomain.com, etc.clientdomain.com all resolve but without redirecting the URL.
Their argument is that this is good SEO practice and that if it don't like it, it's down to me to sort out with a .htaccess redirect.
My argument is that it's poor SEO practice and they should drop the wildcard subdomain from the DNS. Why is it bad practice (in my opinion)? If a user mistypes the URL in a browser, they land on a valid page, no harm in that. However, if they then link to subdomain, then the chasm of duplicate content opens up.
