Do you get IP with DHCP?

If not, I think it would be possible to stop/start pppd without
dropping the connection. I don't know about dhcp.

The ISP sets the IP to "expire" after a certain amount of time. I'm not sure if
this is only because it is an Ethernet connection, or what. But in a network,
you can set the time limit in which an IP will expire. This is often due to
having more users than available IP addresses.

So when "cable guy" came to install the line/router, he told me to hit refresh
(in windows) once per hour. Now, once per hour seemed a lot to me, but after
some reading on the net, I saw that it is not too uncommon for some ISPs to set
the expiry to every 15 minutes or 1/2 an hour, etc. I think its done to make
sure that you are active online and not hogging the address that could go to
others. Kind of like an ISP dropping a dialup connection if there is no activity
after a certain amount of time. Especially in Japan with a cable modem, most
people would want to be online all the time. The ISP expires the IP in order to
keep you from having a virtually static IP address without paying extra for the
service. :-)

I'm not sure I understood what do you mean by 'renewing/refreshing',
is this about dynamic IP address obtained from ISP?

If so why do you want to renew it?
