Soon we are having SIMS SLG installed with capita hosting. When we get the URL for the site it's in some massively user unfriendly format such as http://hslgxx.capita-cso.co.uk/schools/xxxx/SLG
As this is not that catchy I was wondering about setting up a alias in my own DNS that was a bit easier such as http://slg.schooldomain and then pointing it to the site name I was given.
Now this is where my DNS/website knowledge gets a little vague. Can I actually do that? I don't what to point at the IP address in case Capita ever muck around whith the IP address. Secondly if I'm resolving to the domain name will I need to get capita to enable the website to support requests to slg.schooldomain? I think yes but I'm not sure.
Any help and advice would be appreciated.
Sorry forgot to mention I'm wanting to do this in our "external" DNS not the one hosted by my servers on site.
