I have a fixed IP address via BT.
When I type the IP address into MxToolbox or similar i get this warning:
BT-UK-AS BTnet UK Regional network
Reverse DNS (PTR) exists and claimes to be: mail.concept-plc.com
Forward DNS for mail.concept-plc.com is: xx.xxx.xxx.xx
Should I be worried about this and if so who do i contact to do anything about it! Concept PLC seem to be a real company.
Are we sharing a fixed IP address?
Thanks for any help.
Solved! Go to Solution.
Unless you are a business customer you do NOT have a fixed IP address from BT.
This will only really be an issue if you are hosting a mail server on your line. If you are using a business circuit you should ask BT to update the rDNS record to match the hostname of your server as it appears in its MX record.
As licquorice says, if you don't have a business circuit you don't have a fixed IP.
It is a business line and so i do have a fixed ip - an sql server on website needs to talk to my server.
but we don't have a mail server.
Ok, I'll try and find someone in BT who might know what to do.
