Fun fact, most of those break if you just close the connection when the client doesn't support SNI.

- shittyadmin 8y agoNot quote the ones I was referring to - many services just look at DNS and get the A record for every domain then offer reverse lookup - complete lists of domains are purchasable for all major TLDs. The only defense to this would be to host your content on a subdomain. DNSlytics, DomainTools, W3Advisor and others offer this.
- Ayesh 8y agoIt's also easy to just scan a whole range (say, top 1m Alexa domains) and log the IP. You can scan 1m sites on a cheap $5 VPS nowadays.
