Resolved How to check if my DNS record for ssl can be resolved externally

[brownbag]

When I issue a new certificate using Lets encrypt, I get a message indicating that I should add a DNS record then "before clicking 'Reload', make sure that the DNS record was added and can be resolved externally'. The link takes me to a page that doesn't tell me how to check that the DNS record can be resolved externally. So how do I verify the DNS record. I'm guessing that I somehow use the nslookup command but what would the parameters be?
TIA.

you can use nslookup or dig;

nslookup -type=txt _acme-challenge.domain.tld
dig -t txt _acme-challenge.domain.tld

nslookup -type=txt _acme-challenge.domain.tld
dig -t txt _acme-challenge.domain.tld

However this needs to be done from another machine 'cause otherwise you'll only see how it resolves internally.
