The ShieldsUp (grc) test passed, but before running the test itself gave me
Quote Your Internet connection's IP address is uniquely associated with the following "machine name":
xxxxxxx.plus.com
The string of text above is known as your Internet connection's "reverse DNS."
where xxxxxxx is my account name!
Is there any way of preventing that?

Raise a ticket asking that the rDNS doesn't go back to your account name
Mine is now <ipaddress>.plus.com

Quote Your Internet connection has no Reverse DNS
Many Internet connection IP addresses are associated with a DNS machine name. (But yours is not.) The presence of "Reverse DNS", which allows the machine name to be retrieved from the IP address, can represent a privacy and possible security concern for Internet consumers since it may uniquely and persistently identify your Internet account — and therefore you — and may disclose other information, such as your geographic location.
When present, reverse DNS is supported by Internet service providers. But no such lookups are possible with your current Internet connection address (xxx.xx.xxx.xx)That's generally a good thing.

I will submit a Ticket but as noted elsewhere the default should be not to reveal the username
PS edit ~ Ticket submitted and indeed I asked why the default is to show the Username i.e. what logical/legitimate reason can there be for this to be so???

The logic probably is PN email addresses are anything@username.plus.com and rDNS for static IP are username.plus.com.

Shouldn't something be done about this rDNS problem really? There can't be any valid reason for it not to default to the plain IP address, which is one of the options. Or for the choice to be available when requesting a static IP address, which I expect would be a bigger change.

As for it being part of the Plusnet-supplied email address, that's just as bad. It doesn't worry me as I never use it, but ones account username should never be used in any publicly available place. It's probably a hangover from "Noddy" days of innocence :P.
I'm sending a PM as well about a similar issue, so as not to put ideas in anyone's head. I trust existing PN customers, but who know might see posts :).

I have had a reply from CSC and the change has been made and apparently will take 24hours to fully update................do I surmise correctly this relates to DNS progation across the web???
As for the reason for such a default position, well the CSC was also unsure of why this was so but refered to it being so that the user can decide wjat they wish it to changed to!!!! Er!, without casting aspertions on the replier/reply it does seem as Estragon says a legacy issue that has never been addressed. The reply simply says that the default is what it is unless advised otherwise......(by the user??? )
As for the user name appearing in the @addresses for emails.......................well if others such BTconnect.com can simply put the "userchoicename@" before their ISP name then surely PlusNet can do the same. Now this issue has been aired I think in the light of the hacks & compromises on the likes of Sony, FB and Twitter social networking sites the quicker ISP's like PlusNet tighten up the personal security of its customers by default the better.
Why by default....................well not all folk are savvy enough to realise or know that there are risks albeit minor (I hope) to be aware of

But for those still using the ISP webspace to now allow for "informed consent" because like that is a legacy 'product' the web has moved on greatly with consequent increased risk comapred to the "old days"

Quote from: itsme The reason that email addresses are anything@username.plus.com is that in the older days users had web space at www.username.plus.com by default.
That makes a lot of sense :).
Quote As Plusnet no longer offer this perhaps it's time to look at email addresses, rDNS etc again.
Indeed :). Also as Routefinder has replied re the web has moved on.
