# SF patch 809915: In Sep 2003, VeriSign started
# highjacking invalid .com and .net addresses to
# boost traffic to their own site. This test
# started failing then. One hopes the .invalid
# domain will be spared to serve its defined
# purpose.
# Given that both VeriSign and various ISPs have in
# the past or are presently hijacking various invalid
# domain name requests in an attempt to boost traffic
# to their own sites, finding a domain name to use
# for this test is difficult. RFC2606 leads one to
# believe that '.invalid' should work, but experience
# seemed to indicate otherwise. Single character
# TLDs are likely to remain invalid, so this seems to
# be the best choice. The trailing '.' prevents a
# related problem: The normal DNS resolver appends
# the domain names from the search path if there is
# no '.' the end and, and if one of those domains
# implements a '*' rule a result is returned.
# However, none of this will prevent the test from
# failing if the ISP hijacks all invalid domain
# requests. The real solution would be to be able to
# parameterize the framework with a mock resolver.
