No, the result is not the same. When you look up the records for the <yourusername>.github.io you get a different set of records than the singular IP address they tell you to add if you want to use the apex domain!
So from Github's DDoS prevention's point of view, the result is different.
- ninkendo 12y agoSo the answer to the issue is that the IP github tells you to use is the slow one? That sounds strange. What's to stop users from doing their own lookup, and setting their A record to what the result is?
- shawnz 12y agoI believe the reason is that the *.github.io hosts point to a CDN rather than just having a single A record, and it is only when going through the CDN that you bypass the "neutering". Regarding your second question, it seems that github issues a warning if you do that: https://news.ycombinator.com/item?id=7738913 https://news.ycombinator.com/item?id=7738913
