#

# This is a sample HOSTS file used by Microsoft TCP/IP for Windows.

#

# This file contains the mappings of IP addresses to host names. Each

# entry should be kept on an individual line. The IP address should

# be placed in the first column followed by the corresponding host name.

# The IP address and the host name should be separated by at least one# space.

#

# Additionally, comments (such as these) may be inserted on individual

# lines or following the machine name denoted by a '#' symbol.

#

# For example:

#

#      102.54.94.97     rhino.acme.com          

# source server

#       38.25.63.10     x.acme.com              

# x client host 

# localhost name resolution is handled within DNS itself.

# ::1             localhost
