I have a DNS server, where I put A record with TTL set to 0:
Then I do
And get specified ip address. Later I change update record
However, resolved ip is still
While referring to DNS server management UI I see that record has changed, however it is still resolved to old one.
What can cache DNS? I have a dnsmasq service, however it has cache-size set to 0.
Is there any way to detect how DNS record resolved and what causes this behavior? Any ideas? Thanks in advance.
