[Solved] Will systemd-resolved expand nested subdomains? (Answer: No.)

I have some nested subdomains like:

• web01.nyc01.example.com

• mail01.atl01.example.com

I've found that systemd-resolved won't expand these nested domains:

$ host web01.nyc01
Host web01.nyc01 not found: 3(NXDOMAIN)
$ host www
www.example.com has address N.N.N.N

I could just rename them all to top level subdomains like web01-nyc01.example.com, but out of curiosity can systemd-resolved be coerced to expand nested subdomains?

# resolvectl --version
systemd 242 (242.29-1-arch)
+PAM +AUDIT -SELINUX -IMA -APPARMOR +SMACK -SYSVINIT +UTMP +LIBCRYPTSETUP +GCRYPT +GNUTLS +ACL +XZ +LZ4 +SECCOMP +BLKID +ELFUTILS +KMOD +IDN2 -IDN +PCRE2 default-hierarchy=hybrid

This is an explicit design decision
