DNS zone transfer serves to replicate DNS data across multiple DNS servers. It allows secondary DNS servers to obtain updated information from a primary DNS server. This process ensures consistency and reliability within a DNS infrastructure. By allowing secondary servers to synchronize data, zone transfer enhances fault tolerance and improves the overall performance of the DNS system. Additionally, they facilitate load distribution by distributing queries among multiple servers. However, it’s crucial to implement proper security measures to prevent unauthorized transfers, as they could potentially expose sensitive DNS information to malicious actors.
