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.
Example of name resolutions : looking at the host table in Chapter 3.1.3 the
name resolution attempts are:
- as400 : this is not a full name, the resolution is first made with the first
DNS domain (as400.servers.axel.com). Then, in event of failure, with the
second DNS domain (as400.terminals.axel.com). Then, in event of
failure, the resolution is made with the name itself (as400).
- linux : an IP address is associated. No DNS resolution.
- www.axel.com : this is a full name. The resolution is first made with the
name itself (www.axel.com). Then, in event of failure, the resolution is
made with the first DNS domain (www.axel.com.servers.axel.com). Then,
in
event of failure, with the second DNS domain
(www.axel.com.terminals.axel.com).
b) Resolution Method
To resolve a name, the AX3000 sends DNS requests to the DNS server(s).
