Description Petr Menšík 2023-11-28 16:38:36 UTC 
+++ This bug was initially created as a clone of Bug #2251959 +++

During report on bind-utils for RHEL9, it were found dig plugin fails to correctly match name looked for.

It depends on wrong assumption that each record type is delimited by tab. That is not necessary the case.

Reproducible: Always

Steps to Reproduce:
1. dnf install bind-utils nagios-plugins dnsmasq
2. echo 'address=/12-345678example.com/172.23.75.243' > /etc/dnsmasq.d/long.conf
3. systemctl restart dnsmasq
