Static Ip Or Not

Hi all.

When I need to know the IP address on site I just google ' my ip ' or similar. Is their any site I can tell if the connection is static without powering down router and seeing if my IP changes. Sometimes the customer is not sure and has no paperwork and most broadband customer support is a nightmare. On some DHCP connections I can still get the same address even after resetting the router.

Not a great problem,I know, but it would be nice to Know.

You can normally tell from the router config, but not always.

If the IP and subnet are specifically entered it's a fixed IP.

The only way to be 100% sure is to check the ISP setup paperwork which the customer ought to have kept - because if they haven't they're stuffed if the router loses its config.

Or get them to phone the ISP to confirm.

Yeah true you should be able to tell from the router configuration but not always as some still "get" the IP but it's static from the ISP, I think BT is like that will have to check to see if it is sometimes.

Powering down the router, I think the "timeout" on keeping the same IP is something like 10-15 minutes, before it gets reallocated to the pool and given out to someone else even then you might still get it again.

I simple off/on won't probably change the IP.

On my ISP (Be) dynamic IP's rarely if ever change - even if someone goes on holiday and turns it all off.

made the mistake of using BT's dynamic IP addresses for CCTV system requiring dial in...

BT have a habit of doing maintenance at 1am sunday morning, resulting in loss of connection and callouts...

now specify fixed IP's only...

As stated above, the only way to really find out (unless its specified in the router configuration) is to contact the ISP.

So I could be paying for a static IP, not actually have one, and I have to ask the people taking my money if I'm getting what I pay for?

I'm in the wrong job.

It depends what the ISP has set the lease time for IPs to. If it is set fairly long, you will get the same IP each time. If you time out, the IP is released.

On newer IP's with an 'empty' network (ideal for you), you may find they have the lease time set quite high, as there is little point in releasing them all the time.

It's not guaranteed, but the IP may stay the same for a good while, especially if you use a router which re-connects quickly.

Thats the way I have been led to believe it anyway!

The only way to guarantee a static IP is to pay.

In saying that, pipex used to offer it for free, and then for a quid a month......
