More lookups for youtube.com
DNS records map a domain like youtube.com to the servers and services behind it. A and AAAA records point to IPv4 and IPv6 addresses, MX records route email, NS records delegate authority to nameservers, TXT records hold verification and policy data (such as SPF), and the SOA record describes the zone. Values are cached by resolvers for the length of each record's TTL, so a recent change may not appear everywhere at once. To check any other domain, use the DNS Lookup tool.
