Ok I'm confused as hell, it seems http://ctf.1e100.io/ can be typed into a web browser and reached, but has no DNS records or name servers, what's going on here? I don't understand how my web browser is connecting but even if you ping the website it says it couldn't map the hostname.

It has a DNS setting. It's using cloudflare so I really don't understand what you are asking :/

That's the nameservers, what I mean is if you try to ping or scan the site all indicators say couldn't find the hostname which means it doesn't have a DNS record for it yet a web browser can connect to it. I don't understand what's happening here.

I can ping the site:
Code:

Might of been just a type-o

No the servers have changed now since the competition ended, last week you couldn't ping them but could still access them. I guess we'll never know, at least until next year :unsure:

Servers can turn off icmp, which would make ping not work. That might of been the case during the competition.
