What are IP Restrictions?
Our IP Restrictions allow premium customers the ablility to reject specific IP addresses (blacklist) or to allow specific IP addresses (whitelist) to access their workspace. You can find the IP Restrictions page under your workspace's Settings in the left side panel as shown below.
If you don't understand how IP addresses work, you should ask for help from someone in your IT department or contact Support by using the "Help" link at the bottom of this page. There are also some people who should not use the Whitelist feature. See the Questions section below for more details.
Below you can see the two options, Whitelisting and Blacklisting.
Whitelisting
If you enter IP addresses in the Whitelisting field, only the whitelisted IP addresses will be able to see your wiki. Any other addresses on the net will be blocked. You might use this feature to only allow people at your company's IP addresses to access the workspace.
Blacklisting
If you enter IP addresses in the Blacklisting field, you will block anyone at those blacklisted IP addresses from seeing your workspace. You might use this feature if you have determined that there is someone at a specific IP address has intentions to harm your workspace.
Cautionary notes
Normally, you should only use one of these two options. If you are Whitelisting, then the Blacklisting box should be empty and if you are Blacklisting, the Whitelisting box should be empty.
Remember that you should never add your own IP address to the blacklist. You will immediately be blocked from making any changes once you save the setting. If this happens, or if your IP address changes for some reason, you can contact us by using the help link provided below.
We also support CIDR address blocks for those who understand and use them.
Questions?
Are there any reasons why I should not Whitelist my workspace?
If you have an IP address that might change, and you use our Whitelist box to enter that IP address, you may find yourself "locked out" of your workspace. This circumstance applies to all Dial-up internet users and most cable internet customers. Dial-up customers are assigned a different IP address every time they dial into the internet. The greatest majority of cable interernet (broadband) users may not be aware that whenever the cable modem is unplugged or loses power for more than a few minutes, they will likely be assigned a new IP address.

Where can I find more information on CIDR blocks?
A CIDR (pronounced like cider) is a way of defining a whole range of IP addresses instead of listing them all of one-by-one. We use it to make IP whitelisting and blacklisting simpler. An IP address can be assigned to one network, but some networks are so large, they use several IP addresses. If the IP addresses are in sequence, they can be represented in a CIDR. Each number in an IP address is stored in 8 bits, which is why the numbers are between 0 and 255. IP addresses are allocated in large blocks of sequential addresses, so we can use a sort of short-hand known as a CIDR to describe a group of addresses efficiently.
Imagine you have the IP addresses 192.168.0.1, 192.168.0.2, and so on. A CIDR lets you define a range of addresses by specifying the common prefix -- 192.168.0. -- and indicating how much lee way to give in the end of the addresses. For example, 192.168.0.1/8 would include any IP addresses that start with 192.168.0 -- it says that we don't care about the last 8 bits of the IP address. 192.168.0.1/16 would cover all addresses that started with 192.168.
