rrset limits

The rrset limits tag covers discussions about configuring and managing resource record set (RRset) limits in BIND 9 DNS servers, particularly in response to security vulnerabilities like CVE-2024-1737. This flaw can degrade resolver and authoritative server performance when large numbers of resource records are concentrated at a single owner name. Topics include applying ISC patches, enabling RRset limits to prevent exploitation or accidental overload, and operational best practices for DNS administrators. The content focuses on enterprise IT and security concerns related to DNS infrastructure, with emphasis on urgent patching and configuration changes to maintain resolver stability.
