Method 2 (DNS Server)

It's complicated. We recommend Googling "how to set dns servers on <insert distro here>", and making the primary 23.95.137.176
and secondary 1.0.0.1
Don't have administrator or sudo access?
If you're using modern versions of Fabric or Quilt, you can use the regular Cosmetica mod.
