1 year agoA good chunk of the web uses CDNs (content delivery networks) which puts a bunch sites behind the same IP and those gateways rely on SNI to figure out which site to send to the requestor.
CDNs muddy those reverse IP lookups. Encrypted DNS (not from your ISP!) + Encrypted Client Hello are effective in masking what site on a CDN is being accessed.
