Prerequisites

I have checked the Wiki and Discussions and found no answer
I have searched other issues and found no duplicates
I want to request a feature or enhancement and not ask a question

The problem

Background: we use GCPW for people to log into their PC workstations (thousands of them..) .. sometimes 'accounts.google.com' is having issues.. DNS works fine, but for whatever the reason some address results for accounts.google.com are unresponsive and causes issues with logging into the device..

Proposed solution

would there be a way that a syntax could be for a specific TTL for a record (ex: accounts.google.com/+30) would mean that accounts.google.com would only have a TTL of 30 seconds..

accounts.google.com/+fastest

would mean that the responses for accounts.google.com (and only that) would be tested with the 'Fastest IP address' server selection choice..

(presently using these records..)

[/gvt1.com/]h3://8.8.8.8/dns-query
[/gvt2.com/]h3://8.8.8.8/dns-query
[/gvt3.com/]h3://8.8.8.8/dns-query
[/gstatic.com/]h3://8.8.8.8/dns-query
[/accounts.google.com/]h3://8.8.8.8/dns-query
[/accounts.youtube.com/]h3://8.8.8.8/dns-query
[/classroom.google.com/]h3://8.8.8.8/dns-query
[/mtalk.google.com/]h3://8.8.8.8/dns-query
[/m.google.com/]h3://8.8.8.8/dns-query
[/l.google.com/]h3://8.8.8.8/dns-query

Returning results is not the issue.. the results returned are unresponsive.. (which is beyond the scope of DNS.. )

Alternatives considered and additional information

Thank you in advance..

actually the fastest does not add any noticeable lag.. will test with this for a while..

Is it just doing an icmp check of the host?
