The problem

Currently when sorting URLs (say in the DNS rewrites tab), the sorting is done from left to right. This is quite inconvinient as a list of following urls:

• a.tld
• b.tld
• a.b.tld
• b.a.tld
• a.b.a.tld

Will be sorted as follows:

• a.b.a.tld
• a.b.tld
• a.tld
• b.a.tld
• b.tld

A much better way of sorting would result in the following list:

• a.tld
• b.a.tld
• a.b.a.tld
• b.tld
• a.b.tld

Proposed solution

1. Split the strings by the period symbol ("a.b.a.tld" => ["a", "b", "a", "tld"])
2. Reverse the list (["a", "b", "a", "tld"] => ["tld", "a", "b", "a"])
3. Join the elements together with a period (["tld", "a", "b", "a"] => tld.a.b.a)
4. Sort with those keys
5. Reverse the steps before displaying the sorted list

This could probably be optimized but that's the general idea.

Alternatives considered and additional information

It is worth noting that IPs should not be sorted this way. Therefore, if a field can contain both IPs and domains, we have to check first if the contents of a cell are and ip address or not (for example with this regex ^((\d|1?[1-9]\d|2[0-4]\d|25[0-5])\.){3}(\d|1?[1-9]\d|2[0-4]\d|25[0-5])$ (have not tested it))
