Localhost Querying Pihole domain?

[deHakkelaar]

@Scott_Myers

127.0.0.1 localhost

Above line is necessary for the the localhost name to resolve to IPv4 127.0.0.1.
Dont change that one!

Below how is done for Pi-OS/Debian etc:

Sudo: unable to resolve host {hostname}: Name or service not known

Figure out your hostname: pi@ph5b:~ $ hostname ph5b Figure out your DNS search/suffix domain: pi@ph5b:~ $ pihole-FTL dhcp-discover [..] domain-name: "home.dehakkelaar.nl" Edit below file so it resembles: pi@ph5b:~ $ sudo nano /etc/hosts 127.0.0.1 localhost ::1 localhost ip6-localhost ip6-loopback ff02::1 ip6-allnodes ff02::2 ip6-allrouters 127.0.1.1 ph5b.home.dehakkelaar.nl ph5b Check: pi@ph5b:~ $ hostname -f ph5b.home.dehakkelaar.nl
