ariva 200 - mac address

all arivas 200 and 100 have same mac address:
00:80:0f:11:88:88
is it true?
stupid thing for connection to one LAN!!!

improve:
from 1.03B9 all arivas have 00:80:0f:11:70:00
change MAC in tools menu doesn’t work
downgrade = again 00:80:0f:11:88:88
a little bit better than stupid
