ip confusion

[Ryder]

Hi folks

I have just relocated a server to our office.  The server needs to receive data directly from the internet.  Under normal circumstances I would simply buy a few static IPs and carry on... however my director requires evidence that my software does what it says on the box before he goes ahead and starts investing in the measures we would need to run the software long term.

Simple, thinks I (naively).  We connect to the internet, DMZ or port forward the necessary data to the server and show the system in all its glory.  Even with the blistering 2Mbyte speed we are able to attain (being right at the furthest point from the exchange) the software should prove impressive... except the IP changes.  Not when we log on or reconnect as I would expect... but every few hours (if I am lucky enough to go that long).

Is this changing of IP mid session the norm?  I have never had it at other companies I consulot for and certainly not on other networks.

It is a little frustrating because the outcome of this little demonstration could represent a decent payout for yours truly, but I do need to prove it works prior to ordering new systems.

I am open to ideas...

Cheers

Hi,

As far as I'm aware the lease time on dynamic IP is a maximum, but there's no minimum, so there could be any number of reasons why it has changed during the session.  Even if a dynamic IP reaches the end of its lease and changes it doesn't affect your connection, so you wouldn't normally even know about it.

Only thing I can think of is to check what dynamic DNS services are available, for example the handily named Dynamic DNS, which allow you to tack a dynamic connection on to a static host name.

Hope that helps.

Cheers.

it is normal for household broadband, as they don't want you using servers on their network, you could use dyndns, which will update when the ip address changes, setup on router, most now have that facility

2 MByte or 2Mbit ?   

If I take your comment blistering 2Mbyte speed we are able to attain (being right at the furthest point from the exchange)  to be tongue in cheek then it should be 2Mbit (Mb).

If you are are a long way from te exchange and te line is not 100% stable then you could be seeing occasional loss of sync.   Whe te router resyncs you will be allocated a new IP address.

In the 2700's GUI you can find a list of 20 recent events including loss of sync and resync - do they suggest frequent drop outs?   If they do then that is the reason.
