Show ntp associations does not work unless you use the 'no-resolve' flag. DNS is working as expected?

The issue was analysed via PR 1959936.
RCA: The script encountered FCrDNS validation failures when DNS resolution returned no A/AAAA records for the hostname, resulting in rendering failures.
Fix: Hardened the script to gracefully handle DNS responses without A/AAAA records during FCrDNS checks, ensuring such cases are processed correctly without causing script failures.
Restoration:
Correct the Domain Name System (DNS) configuration so that both reverse (PTR) and forward (A/AAAA) DNS lookups succeed.
After the DNS configuration is fixed, both 'show ntp associations' and 'how ntp associations no-resolve' commands work as expected.
Workaround:
Use the 'show ntp associations no-resolve' command to view NTP association information without performing DNS resolution.
Fixed in (and all subsequent releases after these):
evo:25.2R2-S2-EVO evo:26.2R2-EVO evo:26.3R1-EVO evo:26.4R1-EVO
Planned: 24.4R2-S6-EVO
