How to resolve Lame Delegation?
What is Lame Delegation?
A DNS name server is considered lame when it does not adequately respond to DNS queries either by:
- Not responding at all.
- Responding in some way, but not for the specific domain queried.
- Responding to the correct domain, but without the authority bit set.
Lame delegations can lead to:
- Denial of certain services and delays due to DNS malfunctions.
- Timeouts from unresponsive servers that can increase DNS traffic between caching and authoritative DNS servers, resulting in possible load on infrastructure and increased operating costs.
