My system has this:
$cat /etc/resolv.conf search myweb.com nameserver 18.104.22.168 nameserver 22.214.171.124
But when I booted my system(actually in pristine condition) this search line with myweb.com wasn't present.
Did the DNS server add it?
And if it did add it then why didnt all the hosts connected to the same DNS get that search param? It happened only on a few.
