Preparing Change of an IP address

[jochen.wiedmann at gmail.com]

Hi,

we are preparing the change of a web servers IP address. I know, at
that point I have to expect that clients will get a wrong IP address
for a certain time frame. My intent is to get this time frame as short
as reasonably possible.

Currently my zone files have the following header:

@       IN      SOA     foo.com. root.foo.com.  (
                                      2006030500 ; Serial
                                      28800      ; Refresh
                                      14400      ; Retry
                                      3600000    ; Expire
                                      86400 )    ; Minimum

Can anyone recommend good values, which I would enter for a few days?


Regards,

Jochen
