$ dig www.nyu.edu +noall +answer -t A ; <<>> DiG 9.10.6 <<>> www.nyu.edu +noall +answer -t A ;; global options: +cmd www.nyu.edu. 1 IN CNAME dsvdfvx64.github.io. dsvdfvx64.github.io. 2995 IN A 185.199.109.153 dsvdfvx64.github.io. 2995 IN A 185.199.110.153 dsvdfvx64.github.io. 2995 IN A 185.199.111.153 dsvdfvx64.github.io. 2995 IN A 185.199.108.153 Looks like someone added a CNAME record pointing https://www.nyu.edu https://www.nyu.edu to https://dsvdfvx64.github.io https://dsvdfvx64.github.io, but https://github.com/dsvdfvx64 https://github.com/dsvdfvx64 is 404. I wonder how one can use GitHub Pages while the corresponding username doesn't exist.
