AX3000 Models 90 - User's Manual 263
- An incomplete name: no dots are used. The resolution procedure
concatenates another character string to this name (the default DNS
domain name). For more information see Chapter 3.1.2.
Example: "as400" is concatenated with "servers.axel.com" to create a full
name of "as400.servers.axel.com"
A host name is only resolved if the IP address is needed. (i.e. to open a session
or to ping).
Note: a name is resolved for each connection attempt, even if its IP address
has been obtained by a previous resolution.
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.
