I noticed that
gravity.sh creates blocklists that redirect to the Pi’s own IP-address.
dnsmasq (a lot) in the past and I’ve always been told that redirecting clients to the DNS IP or 127.0.0.1 will take longer than a redirect to 0.0.0.0.
That’s because 127.0.0.1 (and the Pi-hole’s IP) will have the client wait for a time-out, while 0.0.0.0 will force the client to drop it immediately.
There are a lot of sources out there that support this practice. I will reference just one here:
I would like to propose a change to create blocklists which use
0.0.0.0 (IPv4) and
:: (IPv6) in stead of the current method.
