DNS Resolve
Overview
The DNS resolver implements a basic DNS resolver according to IETF RFC1035 on Domain Implementation and Specification. Supported DNS answers are IPv4/IPv6 addresses and CNAME.
If a CNAME is received, the DNS resolver will create another DNS query.
The number of additional queries is controlled by the
CONFIG_DNS_RESOLVER_ADDITIONAL_QUERIES Kconfig variable.
The multicast DNS (mDNS) client resolver support can be enabled by setting
CONFIG_MDNS_RESOLVER Kconfig option.
See IETF RFC6762 for more details
about mDNS.
The link-local multicast name resolution (LLMNR) client resolver support can be
enabled by setting the CONFIG_LLMNR_RESOLVER Kconfig variable.
See IETF RFC4795 for more details
about LLMNR.
For more information about DNS configuration variables, see: subsys/net/lib/dns/Kconfig. The DNS resolver API can be found at include/zephyr/net/dns_resolve.h.
