This makes no freakin sense to me, and it’s driving me bonkers. Censored for work purposes obv.

Hosts file:

1.1.1.1 site.com

$ping site.com

PING site.com (1.1.1.1)

^C

$ping http://site.com

ping: unknown host http://site.com

What?? Ping, You JUST RESOLVED site.com, why can’t you resolve it now??

Why does the addition of the protocol break DNS resolution?

It’s CentOS 6.10, quite old…

/etc/nsswitch has:

hosts: files dns

Any pointers would be much appreciated.

    You should deal with problem yourself rather than asking like this. Or forget ping.

    fucking anyone disliking, that guy doesn’t even have knowledge what a hostname and a protocol is. They should learn it themselves. Don’t need to ask.
