Hello,
DNS (Domain Name System) is not only used in cellular data networking, it is a major part of the entire internet. This Wiki page gives information about it.
https://en.m.wikipedia.org/wiki/Domain_Name_System
“An often-used analogy to explain the Domain Name System is that it serves as the phone book for the Internet by translating human-friendly computer hostnames into IP addresses. For example, the domain name www.example.com translates to the addresses 93.184.216.34 (IPv4) and 2606:2800:220:1:248:1893:25c8:1946(IPv6). The DNS can be quickly and transparently updated, allowing a service's location on the network to change without affecting the end users, who continue to use the same hostname. Users take advantage of this when they use meaningful Uniform Resource Locators (URLs) and e-mail addresses without having to know how the computer actually locates the services.”
I hope this helps.
