Hopefully you can help me, I'm looking at adding a few shared hosting packages from different hosts to my little farm, originally, I used my business domain, i.e. mybusiness.co.uk to register by first shared hosting package. Since then I've bought a couple more elsewhere, and registered them initially with another domain, then added mybusiness.co.uk as an add-on, then s1.mybusiness.co.uk as a subdomain. This means I can then add s[n].mybusiness.co.uk ongoing for each shared hosting package I buy in the future.
This seems pretty clumsy in practice, and I'm wondering if theres a better way.
I'd ideally like each shared package I have to be initially registered with s[n].mybusiness.co.uk but it seems every host I try doesnt allow you to register with a subdomain. I cannot expect them to change their config just for me, so I am planning on registering each with the same mybusiness.co.uk - however this wont resolve to each shared host, but to my dedi. Adding s[n] subdomains is fine, but will I have any problems in the future with hosts if the domain I register with doesnt resolve to them? I just want to make sure I'm not going to run into potential problems with hosts/whcms/cpanel etc down the line.
edit: each shared package I use add-on domains to host maybe 5-10 individual sites.
