IP help please!

[artless]

I wonder if you can help me.  I run a very little forum.  One of our members usually posts from an IDNET ip, but recently their ip have been been bouncing all over the world.  When I asked them, they said it was a IP problem, that IDNET had told their customers about it, and it is something to do with going from a static to a dynamic ip.  I have had a look around the forum and can't find a discussion on this.  Is this true, because it sounds very hinky to me!

Thank you in advance.

Hi and welcome to the forum.

I'm not aware of any such issues. What is possible is that your hosting company have blacklisted the IP address due to it being listed on a spam database. If that's the case, the poster needs to talk to IDNet support to try and resolve the matter.

Hi Rik, thanks for the welcome! 

To tell the truth we suspect foul play - proxies or ip hiding software.  But I wanted to check the story, however unlikely it sounds!

[Rik]

Very wise, but I've been in the forum well over five years and never heard a whisper of such an issue. An IP address is just that, no-one knows whether it's static or dynamic for the duration of the session. (Someone will be along to correct me soon. )

That is what was strange.  The IP was the same pretty much constantly, then all of a sudden they are apparently posting from Afghanistan, a school in Essex, Ireland and Bradford. 

I call shenanigans. 

This was the reply from them when I asked why their ip was all over the place:

All I know is we have been told to by our ips that they are changing their systems and we would would get some interruptions. Which we have had like google coming up in German and French . We have just been told to just clear history and cookies then close and reopen the browser if it happens again. I think they are trying to change our ip to dynamic. If you get any alerts again let me know so I can clear everything out and start again.

He/She is messing about with proxies or VPN. Even they had been switched from a static to dynamic IP it would still de assigned from the same pool of available Idnet IP's and not from the other side of the world.

[Rik]

I agree, Griff, and IDNet are not changing to dynamic addressing.

[pctech]

Thought IDNet used static IPs.

A dynamic IP should stay assigned to a connection until either:

The session is lost due to the router resyncing or when using a modem, them disconnecting.

or

The IP lease expiring (standard is around 72 hours) at which point the router would request a new one.

As every ISP have a pool of addresses assigned to them the first two blocks at least should not change if either of the above was happen due to the way routing works.

In Europe (including the UK) the issuing authority is RIPE so it might be worth putting the address into the box on the right of the page available on the right of the page available via the following link http://www.ripe.net/data-tools

This should tell you whether its assigned to IDNet or not

[Rik]

Failing that, PM the address to me and I'll check it.

Done.  You go my forum abuzz!

Good grief, they are now calling me a liar because ID NET don't work on a Saturday and Sunday.

Just to clarify, IF IDNET were rolling out dynamic IP's, you guys would know about it?  And if they were bouncing ip's around the world, you would have heard about it?

Really sorry about this.

[.Griff.]

YES

And if they were bouncing ip's around the world, you would have heard about it?

They aren't "bouncing" IP's around the world.

Thank you.  Sorry to be a pain.  I am going to suggest they join here and call you lot liars.  Dunno why people can't just say "Busted, sorry!".


Will leave you all in peace now.

Again, thank you for your help.

IANA http://www.iana.org who are part of ICANN and who have overall control of IP addressing on the Internet delegate IP blocks regional registries such as RIPE who then delegate them to companies such as ISPs and large coporates.

IANA's site explains in detail how it works.

Unless the person is using something such as TOR which may present a different IP depending on which node the traffic is transmitted from or a VPN the address should indicate it belongs to IDNet when put into RIPE.

If IDNet were presenting addresses that were not from their delegated blocks the responses from your hosting company's servers wouldn't be routed back to the user's machine.

Personally I think this person is either using one of the above and maybe planning to create mischief and at the moment is just testing the water.

Personally I'd just ban them now.

As Mitch has said an Idnet IP would show as such regardless of whether is was static or dynamic. I'm certain we would know if there were changes to dynamic - even it is was new customers only.

Certainly IDNet haven't issued any communications hinting at a change of system.

[pctech]

If anything ISPs are moving toward static IPs so that they are less open to abuse.

[Technical Ben]

I can see where the problem is though. As the mods and admin on this forum can probably tell, using an IP for login credentials could create problems if the IP is being swapped or spoofed... no?

[Rik]

Yes. It's something we monitor closely, but luckily it's not something which often rears its head.
