This article "How to Reset/Restore Hosts file to its Original"

https://www.igeeksblog.com/how-to-reset-restore-hosts-file-to-its-original-version-in-mac-windows/

Explains that one should see the following in one's Hosts file:-

##
# Host Database
#
#
# localhost is used to configure the lookback interface
# when the system is booting. Do not change this entry.
##
127.0.0.1	     localhost
255.255.255.255	broadcasthost


::1		    localhost
fe80::1%lo0	 localhost

-----------------------------------------------------------------

My own iMac shows the following (similar but not identical):-

##
# Host Database
#
# localhost is used to configure the loopback interface
# when the system is booting.  Do not change this entry.
##
127.0.0.1	localhost
255.255.255.255	broadcasthost
::1             localhost

I've read at the link below but am still a little uncertain as to why MY 
"fe80::1%lo0	 localhost"  is missing! <puzzle>

https://superuser.com/questions/241642/what-is-the-relevance-of-fe801lo0-localhost-in-etc-hosts

(I did spot the spelling error "lookback"!)

My question is, SHOULD I reinstate the missing line and space or simply 
leave things as they are?

Advice will be much appreciated.

Thanks.
