Information about DNS and network
Google tried to index URLs on my site like the following: imap.example.com/about.php smtp.example.com/index.php mx1.example.com/index.php The URI paths are actual pages on my bare example.com website, but these combinations of subdomains and paths are not linked from any other website so I assume Google is trying to index them purely on the off-chance that there might … Read More “Prevent Google from speculatively trying to index mail-related subdomains?” »

The problem is as follows: From a few days ago, without any changes, my main domain at https://mydomain.com started not being reachable anymore, while any subdomain, that points to the same IP-address and VPS hosting, is still reachable without any issues. I … Read More “[HELP NEEDED] Main domain not reachable, but subdomain on same host is.” »
I am transferring a client’s domain away from Wix. I want to use Cloudflare, but they do not allow transfers in without first changing the nameservers to Cloudflare’s nameservers. Unfortunately, Wix does not allow you to change nameservers.

This might be a dumb question, but I’m having trouble wording this to get the right answers on Google. Is there a “zero-trust” or roundabout way we can point our primary domain(which is also used for our email) to something-then points to the webhost? Some context: A company I’m helping out has DNS hosted through … Read More “A record pointing to third party managed webhost” »
