:-) I know.  Thats what that "/s" (short for "end of sarcasm") is all about.

... and also the paragraph below (which describes lease renewal)

Nope.   Its your *modem* which is the deciding factor here (the one which
holds the wan IP, not some intermediate router).

But in the case you actually ment "modem" where you mentioned "router": It
can just send lease renewal messages, and all would be well -- you could
keep a fixed IP for as long as your modem doesn't loose its connection to
the ISP.

Almost, but not quite.  Renewal does not mean you drop the IP you have and
do another "I do not have an IP, please give me one" request, it means that
you are requesting *an extension* of the one you already have (you are
sending your current IP as the one you would like to get).   Most DHCP
systems will honor it.

Ofcourse, as some ISPs do not really like you having a fixed IP for some or
another reason, several have introduced the "lets reset the connection
somewhere after midnight", meaning that your modems IP changes at that time,
even when it did not loose its connection.

Bottom line: I don't think that any of them will be daft enough to just
reset the connection when they feel like it, as it would create havoc for
*all* kinds of communications (including the already-mentioned gaming
sessions, but also phonecalls, movie/music stream, etc), especially SSL
connections (they would just be terminated). They would loose customers in
droves.

Power-cycling the modem will most often cause the same result (in other
words (very) short disconnections often do the same (unless the ISP has some
kind of "lingering" implemented).

One word: Whoosh! (it went over your head).

But yes, it has got *nothing* to do with the connection.  Which was exactly
what I tried to convey there (sarcasm and all that).
