Description: Record synchronization ensures that DNS records are consistent across multiple servers. This process is fundamental for maintaining the integrity and availability of online services, as it allows changes made on one DNS server to be reflected on other servers in a timely manner. Synchronization is carried out through zone transfers, where resource records such as A, CNAME, MX, and TXT are copied from a master server to one or more slave servers. This ensures that regardless of which server is queried, the returned information is the same, avoiding discrepancies that could cause connectivity or accessibility issues. Additionally, record synchronization is essential for redundancy and disaster recovery, as it allows multiple servers to handle DNS queries, distributing the load and improving system resilience. In the context of DNS services, this functionality is seamless, allowing users to manage their records efficiently and ensuring that changes propagate quickly across the infrastructure, resulting in a robust and reliable DNS service.
