[DNS]ドメインのMX,TXT レコードの確認方法

Sep 8, 2018 | 1 minute read

mxやtxtレコードのバックアップを撮りたいときがあります。 nslookup -q=anyでとってこれます。　cnameなどはFQDNを知らないと取れないので漏れなく全レコードをバックアップをとるのは難しい？

$ nslookup -q=any gsacademy.com
;; Truncated, retrying in TCP mode.
Server:         100.115.92.193

gsacademy.com   nameserver = ns31.domaincontrol.com.
gsacademy.com   nameserver = ns32.domaincontrol.com.
gsacademy.com
        origin = ns31.domaincontrol.com
        mail addr = dns.jomax.net
