There is no need to make any changes to your domain until your Singlepage website is ready to go live. In fact, up to this point you may be using the domain name for your old website and email, which will be hosted elsewhere.
When your new website is ready to go live, some DNS (Domain Name System) changes will need to be made. You can ask me to do this for you - but if you prefer to deal with this yourself, this page describes the process.
Briefly, this will require you to log into your account at your domain name registrar and change some DNS settings as described below.
The changes you need to make depend on whether you will be using Singlepage for website and email services; or just for the website.
It may or may not be necessary for you to enter the IP addresses of the nameservers - that depends on your registrar. It normally takes several hours for your nameserver changes to take effect, and it can take up to 48 hours for the change to fully propagate around the internet.
Please note: When your nameservers are updated, any email addresses that you currently use on that domain will no longer work and any emails stored on the old mail server will no longer be accessible. In order to continue using those email addresses, you will need to ask us to create the relevant mailboxes in your new Singlepage hosting account - but any emails stored on the old mail server will no longer be accessible. Alternatively, if you wish to continue using your old mail server, you can just update the A-record for your domain instead of updating the nameservers (see below). Also, if you have set up any other special DNS records (e.g. for sub-domains), these will be lost when you update nameservers - so again you may want to update just the A-record for your domain instead of updating the nameservers (see below). Or contact us to discuss these DNS issues before making any changes.
If you no longer have your login details for your account at your domain name registrar, you will have to contact them and ask them to re-issue these details. Or you could simply ask them to make the DNS changes on your behalf (but wait until your Singlepage site is ready to go live).
If you're not even sure who your domain name registrar is, you can do a WHOIS search for your domain:
