Hi,
I am newbie to Fedora and I would like ask
for a (for
me important) clarification regarding the assignment
of the IP address of the computers of my
LAN.
Having problems to
access to a repository located on another computer on my LAN, I used,
several times, the ping command to check the accessibility of the
nodes in the
network ...
With my surprise,
the answers that I received
using the ping command
(with IP number) had
not been consistent.
...an IP number
available at a certain time was no longer available some time after
(and vice-verse);
And
happened also
that non-existent
IP addresses in the network occurred as
available, ...some
times....
Moreover,
a test done with /sbin/ifconfig
stated that some
IP addresses changed in the time..
...
[angelo@zorro ~]$ /sbin/ifconfig
em0:

netmask 255.255.255.0 broadcast 10.0.0.255

I
didn't expect a such (for me)
strange situation, and I would like to have some explanation
about it.
I can only think that
all can be
correlated to the dynamic
assignment of the IP address (DHCP),
but the change of the IP happen also if the computers are not
rebooted.
If, is possible, I should like have a reference to documentation that can explain this my problem.
Thank you
Regards
Angelo
