Multiple IP Addresees - Known Issues, Cautions, and Warnings
Known Issues, Cautions, and Warnings
Following are descriptions of known issues, cautions, and warnings which may apply to the new feature described in this document.
Your Responsible Use of IP Addresses
FreeBSD MPS v3 supports IP version four (IP v4) and is available in the San Jose, California and Sterling, Virginia
datacenters located in the United States.
All IP addresses are on loan from a Regional Internet Registry (RIR). The number of the IP addresses on loan can vary and
is solely based on the requirements you demonstrate and document at the time you request them. Your name and justification
for utilizing each IP address may be disclosed to certain registries, including, but not limited to, the American Registry of
Internet Numbers (ARIN). For more information refer to the ARIN Web site (http://www.arin.net/index.shtml). The ARIN Web site
includes a Search WHOIS feature.
The guidelines regarding your responsible use of IP addresses are offered with guidance from various Internet Engineering
Task Force (IETF) documentation as well as the regional registries. The guidelines are subject to change in the future. For
example, ordering systems for additional IP addresses will be updated to ease the burden of disclosing and demonstrating your
requirement to use an IP address. All future updates to the policies and procedures will be based upon the following guidelines:
- Conservation
- The objective distribution of globally unique IP address space according to the operational needs of customers. No
stockpiling designed to maximize the utilization of IP address space is acceptable.
- Registration
- ARIN requires information on which entity is using an IP address. This information includes: your name, company name
(if a business), postal address, email address, IP address, and telephone number.
- Routability
- The distribution of globally unique IP address space in a hierarchical manner, which permits scalability in the internet
routing table.
Configure Provisioned IP Addresses Only
When configuring your subhosts and certificates, do not specify different IP addresses than the ones associated with your
server. If you do, your subhosts and certificates will not function. This is true of any IP addresses, even those you might
see displayed as unused IP addresses for the subnet of your server. Your server will not function with any other IP addresses
and you will not be able to see information about any aspect of the data traffic associated with any other IP addresses.
The FreeBSD operating system supports a standard, UNIX command which enables you to see the status of network interfaces for
your server. Use the command for diagnostic and configuration tasks. For example, if you issue ifconfig command without any
additional argument, all of the currently active interfaces are displayed. If you issue the command with the additional
argument of -a, all of the interfaces, including inactive ones are displayed. Beyond the simple display of interfaces, the
command includes additional arguments which enable you to specify IP addresses for each of the network interfaces. If you do
specify another address in error, the remedy is to log into your server as root and use the ifconfig command to specify a
correct, provisioned IP addresses. For more details about the ifconfig command, refer to the FreeBSD operating system Man Pages.
CPX: Control Panel and Multiple IP Addresses
With this release, you can configure Multiple IP Address settings with the assistance of the command-line interface your
server offers. The ability to utilize the CPX: Control Panel to configure multiple IP address features is coming soon.
North America Data Centers Only
