We should probably introduce a longer chain of fallbacks in the nervous resolver, but, for now, using the IP address is good enough because it can protect us against the whole DNS being down. This happened to me in Italy, when "Vodafone rete sicura" had several hours of outage and the default DNS was not working as intended, while there was IP connectivity. Reference issue: ooni/probe-engine#88
