About Squarespace Domains
Squarespace Domains II LLC is the accreditation that Google Domains used to operate as Google LLC. Squarespace took over that business in 2023, so domains originally bought from Google Domains now show this name with the same IANA ID, 895.
What the record looks like
A gTLD WHOIS answer carries the two "Registrar" lines below; RDAP carries the same facts as an entity with the role "registrar" and a public ID of type "IANA Registrar ID". The domain here is a reserved example; the registrar lines read "Squarespace Domains II LLC" and 895.
