ipv6domains

IPv6 readiness tester for DNS domains

Currently just a basic POC of reproducing ip6.nl with Go.

build and install

go install github.com/LaFibre-info/ipv6domains@latest

or clone the repo and go run main.go

usage

launching ipv6domains without argument will start a HTTP server listening on port 3000.

Use -a [address]:port to change the port and/or the address to listen on (example: ipv6domains -a :8080)

If at least one argument is passed, the program will work in CLI mode and will display the result for the argument(s) (examples: ipv6domains google.com)

if -check mode is passed, the program runs in batch mode and expects to read a list of domain names from the standard input. It will then processes each domain name based on the mode value:

• 4 : only output the domain names that are IPv4 only (A or www A entries and no AAAA or www AAAA entries)
• 6 : only output the domain names that are IPv6 only (no A or www A entries and AAAA or www AAAA entries)
• 1 : only output the domain names that have errors
• any other non zero value: output number of entries for the following: A, A for www, AAAA, AAAA for www

This is done in parallel using max njobs workers at a time (use -njobs n to change this)

dev

use -web path to use a local web root path instead of the embeded fs (handy to live reload modifications to the templates / html files)
