Safari忽略了macOS High Sierra上的/ etc / hosts

Question

I tried to use /etc/hosts file to redirect some websites to localhost. To do so, I opened it in terminal using sudo nano /etc/hosts then I modified the file, and saved it. As the last step I flushed the DNS cache with sudo killall -HUP mDNSResponder .

Here's what my hosts file looks like:

$ cat /etc/hosts
##
# Host Database
#
# localhost is used to configure the loopback interface
# when the system is booting.  Do not change this entry.
##
127.0.0.1 somethig.com
127.0.0.1 localhost
255.255.255.255 broadcasthost
::1 localhost

This simply doesn't work. I tried to reboot, without luck. I also did a lot of research but did not find any working answers on the internet. Does the OS still use this file, or will this never really work?

I'm using macOS 10.13.

I believe that you need to also override the IPv6 address for "something.com". Do this by adding the additional line "::1 somethig.com". So far as I can figure out, restarting Safari is also required. (You may also need to flush the DNS cache via the method you mentioned.)
