The IP addresses for B.ROOT-SERVERS.NET have been updated to

Security Fixes:
Validating DNS messages containing a lot of DNSSEC signatures
could cause excessive CPU load, leading to a denial-of-service
condition. This has been fixed. (CVE-2023-50387) [bsc#1219823]
Preparing an NSEC3 closest encloser proof could cause excessive
CPU load, leading to a denial-of-service condition. This has
been fixed. (CVE-2023-50868) [bsc#1219826]
Parsing DNS messages with many different names could cause
excessive CPU load. This has been fixed. (CVE-2023-4408) [bsc#1219851]
Specific queries could cause named to crash with an assertion
failure when nxdomain-redirect was enabled. This has been
fixed. (CVE-2023-5517) [bsc#1219852]
A bad interaction between DNS64 and serve-stale could cause
named to crash with an assertion failure, when both of these
features were enabled. This has been fixed. (CVE-2023-5679)
[bsc#1219853]
Query patterns that continuously triggered cache database
maintenance could cause an excessive amount of memory to be
allocated, exceeding max-cache-size and potentially leading to
all available memory on the host running named being exhausted.
This has been fixed. (CVE-2023-6516) [bsc#1219854]
Removed Features:
Support for using AES as the DNS COOKIE algorithm
(cookie-algorithm aes;) has been deprecated and will be removed
in a future release. Please use the current default,
SipHash-2-4, instead.
