WampServer

good day to everyone.

in the past i have asked for a support to my problem, without any efficient solution.

i have set up wamp on a central pc to share an private website with all the other pcs in the net of the office.
the first solution was to copy the modified host file in each pc in order to have the website viewable from each browser.
the matter borns if we have to reset the central router: changing each IP the hosts files need to be re-updated each time.
not efficient at all.

using the PC name is not fast, i would rather say it is FAR TOO SLOW making almost impossibile to use the internal site.

is there any other solution?

is not there any chance to add a RANGE of IPs to the configs files and to the hosts file in order to be somehow safer when i reset the router?

thank you.
