Question: I've heard that there's a new rndc command in BIND 9.11.0 - 'rndc nta'.  What does it do? Answer: 'rndc nta' is used to temporarily disable DNSSEC validation for a domain, allowing unsigned and/or non

domain-name-servers for DHCPv4 vs. dns-servers for DHCPv6). The subnet configurations are very similar aside from the opening stanza being subnet6 vs. subnet4 for DHCPv4, and IPv6 addresses appear instead of IPv4 addresses. Two more differences are

Forwarding can be configured globally and per zone. This is useful where the global policy differs from the configuration required for some of the zones hosted or handled by the nameserver. Many combinations are possible, including no global forwarding except

CVE: CVE-2023-4236 Document version: 2.0 Posting date: 20 September 2023 Program impacted: BIND 9 Versions affected: BIND 9.18.0 -> 9.18.18 BIND Supported Preview Edition 9.18.11-S1 -> 9.18.18-S1 Severity: High

Although not commonly used, the BIND 9 package contains provisions to allow systems to resolve names using the lightweight resolver protocol, a protocol similar to (but distinct from) the normal DNS protocols. The lightweight resolver protocol can be used either

If a server receives a TCP connection on a port that has been configured for communication with a failover peer, this can cause it to become non-responsive to all normal DHCP protocol traffic. CVE:  CVE-2010-3616    VU#159528

DNS cache snooping is a technique that can be employed for different purposes by those seeking to benefit from knowledge of what queries have been made of a recursive DNS server by its clients. Uses of this information vary, ranging
