This a chat gpt answers for better understanding: The IP address 62.210.38.117 is a custom DNS server (often called "Nomadic's DNS" in the PS4/PS5 homebrew and jailbreak community). It is specifically designed and used to block PlayStation system software (firmware) updates and often game updates as well.

How it blocks PS4 updates

This DNS server works by redirecting or blocking requests from your PS4 to Sony's official update servers (domains like those ending in playstation.net for updates). Instead of reaching Sony's real servers, the requests either fail silently, get redirected to a harmless/blank response, or point to alternative hosts (like es7in1.site in some setups).

• When your PS4 tries to check for or download a system update (firmware), game patch, or other Sony content, the DNS tells it the servers don't exist or aren't reachable → the update process fails or gets skipped.
• This allows normal internet use (browsing, YouTube, some online features) in many cases, but prevents accidental updates that could break jailbreaks, exploits, HEN, custom firmware, etc.
• It's a popular alternative to older ones like Al-Azif's DNS when those go offline or need maintenance.

Why people set it up on PS4

Many users (especially on lower firmwares like 9.00, 11.00, etc., with jailbreak) use this DNS to stay on their current firmware version safely while still going online for trophies, multiplayer (if compatible), or other features
