Make the maximum number of processed delegation nameservers configurable via the new 'max-delegation-servers' option (default: 13), replacing the hardcoded NS_PROCESSING_LIMIT (20). The default is reduced to 13 to precisely match the maximum number of root servers that can fit into a classic 512-byte UDP payload. This provides a natural, historically sound cap that mitigates resource exhaustion and amplification attacks from artificially inflated or misconfigured delegations. The configuration option is strictly bounded between 1 and 100 to ensure resolver stability. |
