dhcp assigned IPs and xhost giving me ***** ... :P

[rune]

hey there, help is much appreciated on this noob question:

i would like to be abe to start my computer in runlevel 5, so its graphical, and after i log into my system, i insert my wireless card and get an assigned IP from the dhcp server. but as my ip changes, the xhost now blocks my connection to the client because of the different ip, and then i can't open new programs.

so... i woud like to keep xhost access control enabled, how can i change what the x windows remembers as my ip so that it will allow me to open to windows after i change the ip?

ps. (it would be good if i knew what ip i could be assigned in advance i can xhost +newip, but i dunno the dynamically assigned ip)

thanks for your help friend.
