W niektórych pracowniach na Politechnice na serwerach DNS zablokowane są
„niewygodne” domeny — „*.nasza-klasa.pl” i „gmail.com”. Okazuje się jednak,
że wystarczy sobie zdefiniować odpowiednie domeny w pliku HOSTS,
a wszystko działa pięknie. Poniżej potrzebne definicje.

# 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
