Redirection to PTR records from A,AAAA records
Address column in A, AAAA DNS records was exented of redirection capabilities.
Redirection dialog is shown after a click on a value.
Dialog does following steps:
1) fetch all dns zones
2) find most accurate reverse zone for IP address
2 -fail) show error message, stop
3) checks if target record exists in the zone
3 -fail) show 'dns record create link', stop
4) redirects
Click on 'dns record create link':
1) creates record
1 -fail) show error, stop
2) redirects
