DHCP options
You can configure the following options in the DHCP server:
Option Description
Option 1 Specifies the subnet mask of the network.
Option 3 Specifies the gateway IP address list. The list can contain up to 127 total ASCII
characters. Separate more than one IP address with commas with no intervening
spaces.
Option 6 Specifies the DNS server address list. The list can contain up to 127 total ASCII
characters. Separate more than one IP address with commas with no intervening
spaces.
The phone supports DNS and the dotted decimal addresses. The phone attempts to
resolve a non-ASCII-encoded dotted decimal IP address by checking the contents of
DHCP Option 6. At least one address in option 6 must be a valid, nonzero, dotted
decimal address, otherwise the DNS address fails.
Option 12 Specifies the host name.
