I've read many posts that talk about similar problems but anything has worked for me. When I try to enter github.com it says:
No se puede conectar
Firefox no puede establecer una conexión con el servidor en github.com.
I've tried with other browsers and happens the same. (now I'm using Firefox Quantum). I've done host with github:
$ host www.github.com
www.github.com is an alias for github.com.
github.com has address 192.30.253.113
github.com has address 192.30.253.112
github.com mail is handled by 5 alt2.aspmx.l.google.com.
github.com mail is handled by 1 aspmx.l.google.com.
github.com mail is handled by 10 alt3.aspmx.l.google.com.
github.com mail is handled by 10 alt4.aspmx.l.google.com.
github.com mail is handled by 5 alt1.aspmx.l.google.com.
and:
ping -c 3 www.github.com
PING github.com (192.30.253.113) 56(84) bytes of data.
From 192.168.254.100 icmp_seq=1 Destination Host Unreachable
and: traceroute www.github.com
traceroute to www.github.com (192.30.253.113), 30 hops max, 60 byte packets

but with google everything is fine:
$ traceroute www.google.es
