• View the complete block history for any IP address or IP range, including all encompassing range blocks.
• Adds several quick navigation links for IP ranges.
• Calculate the smallest CIDR range to cover multiple IPs by selecting IP addresses on the contributions page for any IP range or using a standalone calculator.
• Displays a synthetic user talk page for IP ranges by including recent talk pages for individual IPs within the range.

• On individual IP contributions pages, adds a link to a synthetic talk page for an IP range (/24 for IPv4 and /64 for IPv6). When viewing contributions for an IP range, a link to a synthetic talk page for the current range is provided.
• Inserts a (ranges) link next to block log to show the full history of blocks and range blocks affecting the IP or IP range.
• Inserts links for several useful IP ranges (e.g., /16 and /24 when viewing a single IPv4 address).
• When viewing an IP range, a Range selector tools link allows selecting multiple IP addresses to calculate the common range. A Range calculator tools link to a standalone IP range calculator is also provided.

• When viewing the block log for an IP or range, a Find range blocks link is added (similar to the (ranges) link mentioned above).

• Special:BlankPage/RangeCalculator (only available after installation) is the standalone tool to enter IP addresses and calculate the smallest covering range.

The script creates synthetic user talk pages for IP ranges. These pages aggregate relevant recent discussions for a range of IPs. Any edits or additions should still be made on the user talk page for an individual IP.

To install the RangeHelper.js script, follow these steps: {{Ordered list|In your preferences, go to {{myprefs|Gadgets}}. At the bottom of the "Advanced" section, click the "{{delink|{{int:Gadget-script-installer}}}}" checkbox, then click the "Save" button.|Return to this page and click the blue "Install" button.}}

Alternatively, you can manually install it by adding the following code to your common.js file:

None.

• Range queries and calculations are limited to the maximum sizes for IPv4 and IPv6 blocks. Separate calculations are required for mixes of IPv4 and IPv6 addresses and excessively broad ranges.
• When viewing range blocks, blocks smaller than the current range (with larger netmask numbers, such as individual addresses) are not displayed. For example, if you're viewing range blocks for a /48, blocks for /64 ranges or individual IPv6 addresses within the range won't be shown.
• Large range blocks can affect many users and should be used with caution.
