# FIXME: Don't ignore all errors here.  We want to soft-fail (exit 77)
# on 1) when getaddrinfo cannot lookup the address at all, or 2) when
# the canonical address does not contain a period.  Both are
# configuration issues, and the tool is arguable correct to fail in
# these situations.  All other errors should lead to hard failures.
