This may be an odd question but I’m trying to figure out if you can control the IP that your system host-name and domain resolve to. By default they resolve to 127.0.1.1 and adding a static host entry doesn’t override it.
set system host-name fw1
set system domain-name example.org
commit
save
exit
nslookup fw1.example.org
Server: 127.0.0.1
Address: 127.0.0.1#53
Non-authoritative answer:
Name: fw1.example.org
Address: 127.0.1.1
