DNS QuickCheck

Quickly check DNS settings for the (sub)domain in your current tab, or any domain. The default query returns available A, CNAME, and NS records, and you can also check AAAA, MX, SOA, SRV, and TXT records. A time saver for web professionals who launch and troubleshoot client websites, often without direct access to DNS zone files. Source: https://github.com/arthurktripp/dnsQuickCheck
