Description
Specifies the host name.
AVohhhhhh, where:
• AV stands for Avaya.
• o is one of the following values based on Object Unique Identifier (OUI) derived
from the first three octets of the phone MAC address:
- A if OUI is 00-04-0D
- B if OUI is 00-1B-4F
- E if OUI is 00-09-6E
- L if OUI is 00-60-1D
- T if the OUI is 00-07-3B
- X if the OUI is anything else
• hhhhhh are the ASCII characters for the hexadecimal representation of the last

Specifies the domain name. The domain name is required to resolve DNS names into
IP addresses.
Configure this option if you use a DNS name for the HTTP server. Otherwise, you can
specify a domain as part of customizing the HTTP server.
This domain name is appended to the DNS addresses specified in option 6 before the
phone attempts to resolve the DNS address. The phone queries the DNS address in
the order they are specified in option 6. If there is no response from an address, the
phone queries the next DNS address.
As an alternative to administering DNS by DHCP, you can specify the DNS server and
domain name in the HTTP script file. If you use the script file, you must configure the
DNSSRVR and DOMAIN parameters so that you can use the values of these
parameters in the script.
Note:
Administer option 6 and option 15 appropriately with DNS servers and domain
names respectively.

minimum length is 4 and the length must be a multiple of 4.

exchange the vendor-specific information. Option 43 is processed only if the first code
in the Option is 1 with a value of 6889. The value 6889 is an Avaya enterprise number.
All values are interpreted as strings of ASCII characters that are accepted with or
without a null termination character. Any invalid value is ignored and the
corresponding parameter value is not set.
Specifies the DHCP lease time. If this option is not received, the DHCPOFFER is not
accepted. Assign a lease time of six weeks or greater. If this option has a value of
FFFFFFFF hex, the IP address lease is assumed to be infinite, so that the renewal
