@6Cript The documentation that has been linked to doesn’t say that you DO need an IP address, it says IF your registrar requires. You probably do not need it. IF you do, you would acquire them how it says… (visit our Forums for a verified Support Guide on finding the IP addresses for Netlify’s name servers)
Ignoring that, if you’re completely inexperienced, you first want to determine…
Do you want to:
- Use Netlify DNS
(manage all your DNS records with Netlify)
https://docs.netlify.com/domains-https/netlify-dns/delegate-to-netlify/
or - Use SquareSpace’s DNS
(manage your DNS records with SquareSpace, but point just the ‘site’ records to Netlify)
https://docs.netlify.com/domains-https/custom-domains/configure-external-dns/
If you’re going with #1, then you follow the documentation that was already linked.
You follow steps 1 - 5.
As per the introduction note and Step #4, if you need help doing it in SquareSpace’s UI, you would consult their documentation/support.
The values you would enter are as per Step #3.
Simply ignore the note in Step #5 regarding the IP addresses, (unless you determine that you actually require them), you usually just enter the name servers as provided.
