The snippet is this:

ipval = ( os.environ.get('HTTP_CF_CONNECTING_IP') or 
os.environ.get('REMOTE_ADDR', "Cannot Resolve") )
city = "Άγνωστη Πόλη"
host = "Άγνωστη Προέλευση"
try:
	gi = pygeoip.GeoIP('/usr/local/share/GeoIPCity.dat')
	city = gi.time_zone_by_addr( ipval )
	host = socket.gethostbyaddr( ipval ) [0]
except Exception as e:
	print( "metrites.py => (%s): " % lastvisit, repr( sys.exc_info() ), 
file=open('/tmp/err.out', 'w') )


ipval is suposed to get just an ip address.
ip addresses doesnt change its just number seperated by dots.
the same provider i uses yesterday i continue to use today, i just 
restrated the router and got a new ip address and after the new address 
got assignes to me.

unicode decore error related to host started to happen.
Can someone explain this or have a way to troubleshoot it because this 
error is bugging me for several months now but not all the time just in 
cases liek miens today.
