# Travis version specific build environment specification
##############################################################################

# The "precise" build environment on Travis is in the process of being decommissioned
# see https://blog.travis-ci.com/2017-08-31-trusty-as-default-status
# The "precise=true"+"sudo=required" environment seems to lack IPv6 support.
# According to some tests, all "sudo=required" environments do not support IPv6, see 
# https://github.com/travis-ci/travis-ci/issues/8361#issuecomment-328263113
# The container environments for "sudo=false" support IPv6 localhost [::1] 
# connections for server/client test. Thus, all tests with ENABLE_IPV6=YES
