clabGWDeviceDNSIpv6QueryForDualMode
Module: CLAB-GW-MIB
OID (symbolic): CLAB-GW-MIB::clabGWDeviceDNSIpv6QueryForDualMode
OID (numeric): 1.3.6.1.4.1.4491.4.6.1.2.1
Node type: OBJECT-TYPE
Type: TruthValue
Access: read-write
Description: This object provides control over the DNS queries transmitted by LAN clients when the Router is configured in either 'IPv6 Protocol Enabled' or 'Dual Protocol Enabled' modes. When the value of clabGWDeviceDNSIpv6QueryForDualMode is set to 'true', the IPv4 DNS query will be transport layer re-encapsulated into IPv6 for transmission across the Service Provider's network. When set to 'false', the IPv4 DNS query will be transmitted. natively over IPv4. This attribute has no effect if the router is configured for 'IPv4 Protocol Enabled' mode
What is clabGWDeviceDNSIpv6QueryForDualMode?
This read-write TruthValue controls whether, in IPv6-enabled or dual-protocol router modes, LAN clients' IPv4 DNS queries get transport-layer re-encapsulated into IPv6 for transmission across the provider network (true) or sent natively as IPv4 (false). An admin sets this to match how the ISP's backend DNS infrastructure expects to receive queries in a transitional dual-stack deployment. For example, enabling it lets a LAN client's plain IPv4 DNS lookup traverse an IPv6-only access network segment without being dropped.
