How to Clear Google Chrome’s Mobile DNS Cache?

    DNS, or Domain Name System, is essential to internet architecture. Human-readable domain names, such “,” are transformed into numerical IP addresses for Internet data routing. At each new website, your device queries DNS to find the IP address of the domain name you entered. Operating systems and browsers cache DNS replies to speed up the process and minimize DNS server strain. chrome://net-internals may create complications in rare cases, such as IP address changes or connection fixes. Sometimes, deleting the DNS cache helps. This article explains how to clear Google Chrome’s mobile DNS cache.

    I deleted my DNS cache because…

    IP addresses may change once a website migrates to a new server. Your browser’s cache must expire or be cleaned before viewing the new site.

    Clearing your DNS cache may help fix internet connection or website difficulties.

    Security risks: The DNS cache may list all recent web pages. Clearing it may preserve your privacy, especially on shared devices.

    Clearing Mobile DNS Cache with Google Chrome

    Google Chrome has a DNS cache cleaner. See below for access and usage:

    Check Google Chrome’s latest version.

    Simply type chrome//net-internals/#dns mobile . Enter “chrome://net-internals” into your browser.

    Entrance to DNS: Choose from several options on the left sidebar. The “#dns” hashtag opens DNS.

    In the DNS area, click “Clear host cache.” Flush the DNS cache immediately with this option.

    Recheck the hostnames after clearing the cache. It should be empty or less full.

    Repercussions of DNS Caching

    DNS caching has more than just speed improvement implications:

    Performance Boost: By decreasing the need to continually ping external DNS servers, caching speeds up the loading of internet pages.

    Reduced Network Traffic: By caching DNS replies locally, less DNS traffic is directed over the network, resulting in bandwidth savings.

    Dependence on External Servers: With caching, a user may continue accessing frequently visited websites until the cache expires, even if an external DNS server is down briefly.

    DNS Cache at the system vs. browser level

    It’s vital to distinguish between the DNS cache maintained by browsers like Chrome and the operating system’s cache:

    DNS Cache for Browsers: Each browser has a unique caching method. Chrome’s cache is the only object impacted when the DNS cache is erased. The size and TTL of this cache are generally smaller than the system cache’s.

    The OS maintains a local DNS cache. Neither deleting your browser’s cache nor erasing your cookies will influence this. A restart or specific programs may be necessary to delete the DNS cache on a mobile device’s system.


    Google Chrome on mobile devices makes emptying the DNS cache simple, but understanding when and why to do so is vital. Clearing the DNS cache can help with troubleshooting, privacy, and viewing the latest version of a website. Use caution and a good reason to delete the cache.
