Custom subdomain with project page hosted on Github pages












0















I have already successfully set up a GoDaddy subdomain to point to my personal gh-pages website. This means that my username.github.io webpage is pointing to subdomain.domain.com.



As a consequence of this, all the project gh-pages on my github account are changed accordingly, e.g. a page on repository test-project (which would have been previously hosted at username.github.io/test-project) now is hosted at subdomain.domain.com/test-project.



I would now like to set up my GoDaddy DNS manager in such a way that my test-project gh-page points to a second subdomain, for example project.domain.com.



Now, I know there are plenty of similar questions on stackoverflow, but none of them seems to be solving my specific case. My problem is that I don't know what to add to the CNAME record on GoDaddy. I've tried with both subdomain.domain.com/test-project and username.github.io/test-project , but none of them seems to be working! In particular, if I put username.github.io/test-project, it returns the following error:




Enter either @ or a valid host name such as: "subdomain.domain.tld"




UPDATE
I've solved by following this Subdomain of website for Github pages project and having my subdomain CNAME to point to username.github.io. (notice the . at the end). I will do it for any other future subdomain.



Now my question becomes: what does the . do? What does it mean? It is not very clear to me.
