You changed my static IP without telling me !

[#1]

Had no end of grief late yesterday and today with sites that I maintain that use IP-based intrusion detection and authentication that had my static IP on their whitelist refusing me.
I only just realised that my STATIC IP is now a different number. I'll repeat that again
my STATIC IP is now a different number.
Nothing from Plusnet to warn me that this was a scheduled change.
This is unbelievably poor.
Just a heads-up in case they have been jerking other customers around.

The static IP on your account has been active and not changed for the last two years?

[#3]

I have gone back through some old whitelists and my IP today is the same as it was in 2014, but for the last month it has been a different number. The proof I have of this is that I started using a remote FTP server that uses IP whitelisting to control login access a month ago and it was working until yesterday. I have examined the whitelist entry that allowed me access for the last month on this FTP server's control panel and IT IS A DIFFERENT NUMBER to the one I have currently. To regain access to this FTP server today I had to add another IP to its whitelist - which is the IP number I have today.
They changed - no question - the FTP server whitelist proves it.
What happened ?

[#4]

I've checked your connection logs and they have had the same IP on every connection going back as far as I can review (May), your public IP has not changed in that period.

[#5]

So we have two contesting versions of reality here - If my public facing IP hasn't changed that how do you explain my access problems with this FTP server ?

[#6]

Have you spoken to whoever hosts the FTP server? Maybe they had an issue with the whitelist, or updated it incorrectly. All I can tell you is that the connection IP assigned to your connection has been the same.

[#7]

that's fudge
When I needed to supply my IP to gain access to this FTP server, I supplied IP number A - that immediately allowed me access - before the FTP server was refusing me. So - a month ago, the IP number  I supplied was my public IP
Starting yesterday, the FTP server refused me, so I had to investigate what had changed. I logged into its Control Panel and the whitelist number A I had supplied a month ago was still there BUT it was offering to add another number B - also within the Plusnet 195.166 block - that it had detected as my public IP that wasn't present in the whitelist. I added it and I could immediately access the FTP server again, so my public IP was now IP number B
I fail to see how that sequence of events can be explained by fog like 'issues with the whitelist' or 'updated it incorrectly'

[#8]

I don't know what else to tell you then.
Your connections to us have definitely been on the same 195.166.*.* IP address going all the way back to at least May. There have been no changes to the IP on your account.

[#9]

Can't both be true

[#10]

If you visit www.whatsmyip.org you will see what your IP address is.
Report it back here so that the techies can look into it!

[#11]

I can confirm what Adam and Chris have said as I can see only the one IP on disfroot's posting history.

[#12]

I post here about every 18 months - it has been a long time since my last post. All I have stated above is concerned with a scenario that indicates that my IP has been different for the last 4-6 weeks. As I haven't posted anything here anywhere near that time window, your chip-in about what forum logs you can look at is not relevant.

@nedludd
I don't bother to remember what my IP is - whenever I need to know it, I log into my router and see what the status page says - that's the number I always use.

[#14]

According to your posting history you previously  posted on 25/8/15, 18/6/15, 11/6/15 then a long gap back to 9/3/14
So from what strat has said your IPaddress was the same on all  those posts

[#15]

I have no reason to not believe that - however - where is the explanation for the FTP whitelist behaviour ?
