Managing the IP Exemption List

[Quotes]

Please can I request three changes:

1/ Bulk export and import facility

2/ Comments field

3/ Support for Network Mask

Here's the reason why...
- many of Twitter's mail servers are blocked on List 4 (UCEPROTECT-1)
- for example spring-chicken-bc.twitter.com
- corresponding IP is 199.16.156.168

I can add the IP but it would be useful to add a comment alongside like "list 4, spring-chicken-bc.twitter.com"

However if you search for Twitter IP ranges you can find some of them at http://bgp.he.net/AS13414#_prefixes and they are expressed with network mask such as 199.16.156.0/22; 199.59.148.0/22 etc

It would be easier to use the network mask notation so that I don't have to review the logs and search for individual IPs and apply retrospectively.

At the moment my IP whitelist is as follows:
199.16.156.173
199.16.156.141
199.16.156.155
199.16.156.168
199.59.150.87
199.59.150.90
199.59.150.98
199.59.150.81

As you can see this view isn't very informative, it could be shorter, and it would benefit from an import/export facility
