Downloading the IP Address
You can set the IP address of the Ethernet adapter by using DHCP, ARP, RARP, or
BOOTP. All methods are enabled by default. If you want to disable any of the methods,
you can do so when installing the Ethernet adapter using the AXIS NetPilot Installation
Wizard. For help, see “Setting Up With AXIS NetPilot” earlier in this chapter.
From the Axis Installation Wizard you can also set the IP address manually.
The main characteristics of the supported methods are described below:
Name Characteristics
DHCP DHCP (dynamic host configuration protocol) is available in Windows NT
and UNIX systems and allows for the automatic but temporary assignment
of IP addresses from a central pool. When enabled, DHCP causes the
selected host to automatically allocate and download an unused IP address,
default router address, and net mask to the requesting adapter. It also
provides validation data that defines how long the IP addresses remain
valid.
To fully benefit from this method, the Ethernet adapter also supports the
Windows Internet Name Service (WINS) host name resolution protocol,
which is available in Windows NT networks.
ARP Available in UNIX, Windows 95, Windows 98, and Windows NT, ARP
(address resolution protocol) is an easy method to download IP addresses to
individual adapters. You cannot use this method over routers.
RARP RARP (reverse address resolution protocol) is available in UNIX and it
downloads the IP address to each device automatically. It requires a RARP
daemon on your system and operates within a single network segment only.
A request made to an active RARP daemon initiates a search of the Ethernet
Address Table for an entry matching the adapter's Ethernet address. If a
matching entry is found, the daemon downloads the IP address to the
adapter.
BOOTP BOOTP (bootstrap protocol) is available in UNIX and is quite similar to
RARP, although it can operate on the entire network. It requires a BOOTP
daemon on your system. A request made to an active BOOTP daemon
initiates a search of the Boot Table for an entry matching the adapter's
Ethernet address. If a matching entry is found, the daemon downloads the
IP address to the adapter.
