Quick Response Query for server-fail?

Sukmoon Lee

Hello.

 

I found the slow response query at dns server. This query is server fail response.

In reality, this query gets to response a server fail for foreign dns server.

 

For example, maincastad.com’s glue record has 3 name server, 5 ip address.

All glue record dns is not response. So, this query responses to slow.

 

Is it possible to cache and quick response like ncache(negative cache)?

Thanks.

 

 

$ dig @b.gtld-servers.net maincastad.com
