Question

How do I setup my SBG6580-2 to use another DNS?

Answer

Domain Name Server (DNS) is a database that contains domain host names (e.g http://www.surfboard.com) that are linked to a specific IP address. When accessing a website the computer uses DNS to retrieve the website's specific IP address. Without DNS the computer could only access the specific IP address directly if known. This document describes how to set up custom DNS addresses in the SBG6580-2.

CAUTION: By default, the SBG6580-2 obtains the DNS addresses are obtained automatically from the service provider. Internet connection may be lost if the DNS addresses inputted in the SBG6580-2 are not legitimate.

The following are examples of scenarios when DNS settings are customized:

Users may prefer to use public DNS addresses to improve the web browsing experience.
Advanced users set up local DNS servers in a home network to hide DNS requests.

DNS Setup

Launch a Firefox or Safari browser. Enter http://192.168.0.1 into the address box, and press the Enter key.

NOTE: A browser message on Chrome, Edge, Firefox, and Opera, may appear when accessing the Web Manager. The message includes 192.168.01 uses an unsupported protocol and ERR_SSL_VERSION_OR_CIPHER_MISMATCH. The Web Manager uses an earlier version of the TLS protocol and does not match the version allowed by the web browser. Safari browsers on Apple PC and mobile devices are not impacted. The workaround to access the Web Manager with a PC is to use the Firefox browser and set the TLS version to 1. For workaround instructions refer to article # 19435 - 192.168.0.1 uses an unsupported protocol.
A security or private risk alert may appear on the web browser advising users to proceed with caution when accessing the Web Manager. There is no risk in proceeding to the Web Manager. For instructions to bypass the alert screen, refer to article # 18181 - Alert Message for Web Manager Access.
On the Login page, enter admin or a customized username in the Username field.
Enter password or a customized password in the Password field.

NOTE: On later versions of the SBG6580-2, the Wi-Fi Security Key is used as the default admin password printed on the bottom white label. For assistance with Web Manager Access, refer to article # 18752 – SBG6580-2: Web Manager Access.
