The DNS-based method of transmitting data provides a telecommunication method for transmitting user-selectable data through the Domain Name System (DNS). Selected data is encoded as an alphanumeric character string on a user device. A uniform resource locator (URL) having a domain part and a host part is generated, where the host part is constructed from the alphanumeric character string. The URL is transmitted from the user device to a local DNS server. The URL is forwarded from the local DNS server to an authoritative DNS server associated with a domain name of the domain part. A set of response bytes, which are responsive to the user-selectable data encoded as the alphanumeric character string of the host part, is generated at the domain and transmitted from the authoritative DNS server to the local DNS server. The set of response bytes are transmitted from the local DNS server to the user device.
