Which DNS record type is required to allow APs to discover a WLC using DNS over IPv4?

An A record (Address record) maps a hostname to an IPv4 address. For APs to discover a WLC via DNS over IPv4, they need to resolve the WLC's hostname (e.g., cisco-wlc.example.com) to its IPv4 address. The AP then uses this IP address to attempt communication. NS records (Name Server) identify the authoritative DNS servers for a domain. SOA records (Start of Authority) provide essential information about a domain, like the primary name server and administrator's email. MX records (Mail Exchanger) specify mail servers for a domain. While all are crucial for DNS operation, none directly provide the IPv4 address mapping needed for AP discovery.
