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

# 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

# localhost name resolution is handle within DNS itself.
# 127.0.0.1 localhost
