Name: @
Type: A
TTL: 1h
Data: 185.199.108.153
185.199.109.153
185.199.110.153
185.199.111.153

Type: A
TTL: 1h
Data: 185.199.108.153
185.199.109.153
185.199.110.153
185.199.111.153
In this case the 2cld github netstack repo is hosting the main landing page for netstack.org. This repo has a CNAME file that will allow the github DNS servers to resolve the DNS request to a specific github user repo.
Name: yoursubdomain
Type: CNAME
TTL: 1h
Data: 2cld.github.io.
In this case the 2cld github user would host the “yoursubdomain” repo containing web pages for yoursubdomain.netstack.org. This repo has a CNAME file with “yoursubdomain.netstack.org” that will allow the github DNS servers to resolve the DNS request to a specific github user repo.
