Check whether your /etc/nsswitch.conf has a "hosts: files dns" entry. Without this your machine will not perform DNS lookups for hostnames. Look in /etc/nsswitch.dns file for sample "hosts" entry.

nss-systemd
NSS-SYSTEMD(8) nss-systemd NSS-SYSTEMD(8)
NAME
nss-systemd, libnss_systemd.so.2 - Provide UNIX user and group name resolution for dynamic users and groups.
SYNOPSIS
libnss_systemd.so.2
DESCRIPTION
nss-systemd is a plug-in module for the GNU Name Service Switch (NSS) functionality of the GNU C Library (glibc), providing UNIX user and
group name resolution for dynamic users and groups allocated through the DynamicUser= option in systemd unit files. See systemd.exec(5) for
details on this option.
This module also ensures that the root and nobody users and groups (i.e. the users/groups with the UIDs/GIDs 0 and 65534) remain resolvable
at all times, even if they aren't listed in /etc/passwd or /etc/group, or if these files are missing.
To activate the NSS module, add "systemd" to the lines starting with "passwd:" and "group:" in /etc/nsswitch.conf.
It is recommended to place "systemd" after the "files" or "compat" entry of the /etc/nsswitch.conf lines so that /etc/passwd and /etc/group
based mappings take precedence.
EXAMPLE
Here is an example /etc/nsswitch.conf file that enables nss-systemd correctly:
passwd: compat mymachines systemd
group: compat mymachines systemd
shadow: compat
hosts: files mymachines resolve [!UNAVAIL=return] dns myhostname
networks: files
protocols: db files
services: db files
ethers: db files
rpc: db files
netgroup: nis
