This ensures that your next query fetches fresh data from the nameserver rather than showing outdated local results.<\/p>\n\n<\/div>\n<\/div>\n<div id=\"faq-question-1771837503022\" class=\"rank-math-list-item\">\n<h3 class=\"rank-math-question \"><strong>What is the &#8220;DnsRecord&#8221; object exactly?\u00a0<\/strong><\/h3>\n<div class=\"rank-math-answer \">\n\n<p>Unlike the text output of nslookup the DnsRecord object is a structured data set.
