NsLookup.io VS Whats My DNS

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: 11 months 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: about 1 year ago

Namecheap advanced DNS settings has an A Record with "photos" as the host and my home IP as the value. Visiting whatsmydns.net and checking the subdomain photos.myserver.com is propagated gives me green ticks. Doing a "dig photos.myserver.com" shows it's pointing to my home IP. Source: 12 months ago

You should have virtually 0 in the way of downtime. You can check DNS propagation at whatsmydns.net. That will give you a general idea. Source: about 1 year ago

You can monitor DNS propagation with whatsmydns.net Doesn't make it go any faster, but gives you something to watch - haha. Source: about 1 year ago

I am quite new to the whole topic of email security and today I came across whatsmydns.net and searched for my domain. Since then I realized that some DNS records are open to the public (e.g. Verification and SPF) and others maybe are, too (at least not on this website, couldn't get information about my dmarc entry).

However, after over 4 days whatsmydns.net and other dns checking tools are still showing the websites as not fully propagated, in addition my Vercel websites are still showing as pending and "Invalid Configuration" and my Zoho Mail console is further showing as the domain name configured and "MX Verification failure".
