Https://leakcheck.io/ - Payed, But you get passwords in clear text and there's a cheap 1 time payment option! Source: 12 months ago

Sharing is caring, so I'll share one of mines. I tend to use google dorking as usual, but also use LeakCheck which is a rather handy tool to receive clear text passwords from Usernames, Email Addresses and such. Are there any other places, like these, that can be of use? :). Source: about 1 year ago

You could try https://leakcheck.net/ or https://www.dehashed.com/ (personally best for me) but they are paid unfortunately. Source: over 2 years ago

There was a data breach last year. Check on https://leakcheck.net/ whether your details were on there. Source: over 2 years ago

I think https://leakcheck.net/ might be the one you're looking for. For personal emails I use hacknotice.com. Source: about 3 years ago

I see myself expanding nslookup.io into a wider range of web-based networking tools. More like an integrated web app where you can explore internet infrastructure than a collection of individual tools. Source: about 1 year ago

I am shocked the website is IPv4 only and a check I did on nslookup.io shows petition.eu points to an A record 35.239.211.251, hosted by Google. I am sure Google can provide an IPv6 address if requested, so I do not know why the operator of petition.eu has not requested. Source: about 1 year ago

I used the took nslookup.io to do an nslookup and that website has no AAAA record, meaning it is IPv4 only. Source: about 1 year ago

Nslookup from Unraid gives the server address of my router and [ROUTER-IP]#53 for the address. I failed to mention, I have tailscale set up, could that be an issue? When I did nslookup from my PC, it gave magicdns.localhost-tailscale-daemon as the server. When I did nslookup from nslookup.io, it gives my Cloudflare nameservers. Source: about 1 year ago

Dig also gives matching information as above. Also checked the IP address from an external source (nslookup.io), it's the same. Source: over 1 year ago
