A.4.2 - Resolving a Name

a) Resolution Strategy

To resolve a name, a DNS request is sent by the AX3000. A DNS request

contains the destination DNS server IP address and the name to be resolved.

To resolve a name possibly more than one DNS request is needed (if one or

more default DNS domains are defined). The resolution process is stopped

either when the AX3000 receives a positive response from a DNS server

(success: an IP address is associate to this name) or when all the DNS

requests has been sent and no positive response has been received (failure:

the name is not resolved).

The order of the requests sent to resolve a hostname is called the resolution

strategy.

The resolution strategy depends on both:

- whether or not a domain name is declared,

- whether the name to resolve is complete.

If no default DNS domain is defined in the AX3000 Set-Up, the resolution is

done with the name itself regardless of whether the name is full or not.

If one or more default DNS domains are defined, the resolution strategy

depends on the name:

- Full name: the resolution is first done with this name. If unsuccessful new

resolutions are performed by concatenating the full name with the defined

DNS domains.

- Incomplete Name: the resolutions are first done with the defined default

DNS domains. If unsuccessful a new resolution is performed with this

incomplete name.
