I would like to preface this with another issue, when trying to report this issue (via the give feedback about red hat documentation page) it lead me to here and told me to create a Jira ticket with the create button in the top bar (of which there isn’t one) and there was no suitable category for me to open this ticket that I could find so apologies if this is misplaced.

https://docs.redhat.com/en/documentation/red_hat_enterprise_linux/10/html/getting_the_most_from_your_support_experience/providing-feedback-on-red-hat-documentation 

Please can you update the example config file under “procedure” to have a # between <server_ip_x> and <dns_server_hostname_1>

So instead of:

servers=dns+tls://<server_ip_1><dns_server_hostname_1>,dns+tls://<server_ip_2><dns_server_hostname_2>

It should say:

servers=dns+tls://<server_ip_1>#<dns_server_hostname_1>,dns+tls://<server_ip_2>#<dns_server_hostname_2>

I think the reason for the omission is because systemd-resolved uses hashtags like this too so it’s implied if you are aware of this however as an end user I was just trying to follow the instructions to configure it and was confused when there wasn’t a delimiter between the server ip and server hostname so had to search elsewhere for what the delimiter should be.
