Dynamic DNS is usually used in conjunction with DHCP for assigning
meaningful names to host systems whose IP addresses change
dynamically.
Access Points provide DDNS support by adding the host name (option
12) in DHCP Client messages. The DHCP server uses this option to
dynamically update the DNS server.
Access Point System Naming Convention
The Access Point's system name is used as its host name. To prevent
Access Points that have default configurations from registering similar
host names in DNS, the default system name of the Access Point is
uniquely generated. Access Points generate unique system names by
appending the last 3 bytes of the Access Point's MAC address to the
default system name.
The system name must be compliant with the encoding rules for host
name per DNS RFC 1123. The DNS host name encoding rules are:
• Characters must be alphanumeric or hyphen.
• The name must not start or end with a hyphen.
• The name must not start with a digit.
• The number of characters must be 63 or less. (Currently the system
name length is limited to 32 bytes).
Image upgrades can cause the system to boot with an older system name
format that is not DNS compliant. To prevent problems with dynamic DNS
