It is possible to register a domain name with LetsHost.ie and connect it to your website with Squarespace. To do this, you will need to use the DNS Manager feature in your client area.
First, log in to your Squarespace account and click on Settings - Domains
Click the button for 'Use and domain I own', type in your own domain name and click Next
Click the button for 'Connect Domain'
Select 'Other' from the list and click 'Connect Domain'
Click Continue and then copy/paste the DNS Settings on the following screen
Next, log in to your LetsHost.ie client area (https://www.letshostbilling.com/clien...) and click on Domains - Managed DNS
Click Add New Zone and fill in your domain name and IP Address (as per Squarespace DNS Settings)
Click Add Zone
Click the Edit pen icon and then proceed to add in each of the Squarespace DNS Settings
Click Domains - My Domains
Click the blue down arrow and then Manage Nameservers.
Enter in 'ns9.dnsireland.com' and 'ns10.dnsireland.com'. If there are any other nameservers listed, remove them
Click Change Nameservers
It will take a few hours for the above DNS Settings to take full effect, but afterwards your domain name will be connected to your Squarespace website
