Opened: Dec 12, 2023 Severity: 4-Minor
USC/ISI, which operates b.root-servers.net, renumbered the IPv4 and IPv6 addresses on November 27, 2023. The current IPv4 address is 170.247.170.2, and the current IPv6 address is 2801:1b8:10::b. USC/ISI continues to support the root service over the current IPv4 and IPv6 addresses until November 27, 2024,(one year). This enables a stable transition while new root hints files are distributed in software and operating system packages.
As USC/ISI supports the current IPv4 and IPv6 addresses for a minimum of one year (November 27, 2024), there is minimal impact. A single timeout for pending TLD queries can occur when accessing an old IP address using round-robin. Normally, the hint's TTL which is more than a month can cause a timeout when the old IP stops responding.
Several profiles include the b.root-servers.net
