Summary: Non-proxy hosts
This key contains a list of hosts which are connected to directly, rather than via the proxy (if it is active). The values can be hostnames, domains (using an initial wildcard like *.foo.com), IP host addresses (both IPv4 and IPv6) and network addresses with a netmask (something like 192.168.0.0/24).
Default: ['localhost', '127.0.0.0/8', '::1']
In the array, there must be one and only one while space behind the comma(,).
Or else, the default value can't be restored
