Hello mark,

On Monday September 23 2013 12:19, you wrote to me:

 MvdV>> Never. It is kept alive as long as I keep paying the yearly

No, I don't need that. They supply you with an updater and the folks who's ISP
regularly forces a change of IP need it. I have run the updater in the past but
I have stopped using it as it never did anything because my IP is quasi static.

 ml> what do you do if your IP changes? is it handled automatically or
 ml> manually?

My IP only changes when I change the router. Or more precise, when its MAC
address changes. That won't happen without e knaowing about it, so such a
change is never unexptected. The present router has been in place for a couple
of years.

When I change the router - without cloning the old router's MAC address - I
will get a new IP address. I even get back the old address when I put the old
one back in place. I assume there is a time limit there, coupled to the lease
time, but I never run into that.

Anyway. I can do two things:

1) I can go to their website and manually update the zone file.
2) I can click on the icon for the updater and let it run for a few minutes.

I just run a binkp server and a very simple web server. No mail servers, no ftp
servers. I guess I am not an attractive target.

I heve never seen any attempts like that in the web servers log...

 MvdV>> A call once a minute is annoying because it pollutes the log.
 MvdV>> Otherwise it is pretty harmless.

Yes, large logs can be a nuisance. Information overlaod....

I can see that. But I don't keep the logs that long. I have them trimmed at
regular intervals. In order not to make any bad guys reading this any wiser, I
won't divilge how long I keep te logs, but it is not forever.

 MvdV>> That is what I gathered from previous postings of yours.

Over here that is different. Energy is about four to five times more expensive
here as in the US.

I see.


Cheers, Michiel
