Re: Static IP
I believe rDNS can be configured to one of the following:-
1 - username.plus.com – This is the default setting.
2 - IP.plus.com - 1-1-1-1.plus.com as an example.
3 - anything.domain.com - e.g. mail.bbc.co.uk – To use this option you will need to configure the forward record on the domain. We are required to prove you own the domain before any changes can be made and this will serve as verification. The domain can be hosted on the account or externally.
You used to request it via a ticket but probably best to wait fro one of the PN help team to spot this and advise of the best way nowadays...
Yes it can be configured using one of the above options @MisterW has advised.
