There is currently an ip address widget if you search for "ip address". It shows either your ipv6 or ipv4 (probably depends on how you connect to kagi).
This could be improved by having an ipv6 and ipv4 only domain to check both ip versions, e.g. make a connection to ipv4.kagi.com and ipv6.kagi.com.
Additionally it currently only shows the country, but not a more specific location like city / state (yes I'm aware that ip address locations can't be precise).
It would also be interesting to see more information like ASN, reverse dns, ...
Something like https://ipinfo.io/ does.
It would also be great to get this widget when searching for an ip address like 1.1.1.1
Currently there are the ip location bangs, but these pages are often filled with ads or slow to load.
If it was possible to get this information directly in kagi, by either searching for the address or searching for "ip address", this would be a huge QoL improvement especiallly when being on mobile.
