DNS over SMS

Sometimes you are on the go but just need a DNS answer, stat. Luckily, 1.1.1.1 supports DNS over SMS.

Send a text message to +1(833)672-1001 or +44(0)1807391001. You can send a domain name, which will return the AAAA answer by default.

Example SMS:

example.com

Response:

2606:2800:220:1:248:1893:25c8:1946

1.1.1.1 is a partnership between Cloudflare and APNIC.

You can also send a record type followed by the hostname. The record types accepted by DNS over SMS are:

A
AAAA
CAA
CNAME
DS
DNSKEY
MX
NS
NSEC
NSEC3
RRSIG
SOA
TXT

Example SMS:

TXT dani.cloudflare.com
