Other, less-common forms of records that might exist in DNS have specific purposes, and there might be cause to create them. The following is a sample list, but is by no means exhaustive:
• AAAA—Maps a standard IP address into a 128-bit IPv6 address. This type of record will become more prevalent as IPv6 is adopted. See Chapter 11 “DHCP / IPv6 / IPAM” for more details on IPv6.
• ISDN—Maps a specific DNS name to an ISDN telephone number.
• KEY—Stores a public key used for encryption for a particular domain.
• RP—Specifies the person responsible for a domain.
• WKS—Designates a particular well-known service.
• MB—Indicates which host contains a specific mailbox.
