Network

This page documents the DNS domains used by Switch, and what they're used for. Only HTTPS is used with these domains unless noted otherwise.

• "sun.hac.lp1.d4c.nintendo.net": Used for checking whether a sysupdate is available, equivalent to NetUpdateSOAP from past systems.
• "atumn.hac.lp1.d4c.nintendo.net": CDN for system-titles.
• "tagaya.hac.lp1.eshop.nintendo.net": VersionList for eShop titles going by 3DS.
• "dauth-lp1.ndas.srv.nintendo.net": Seems to break Nintendo-account related comms when blocked. This dauth domain seems to be the cause of the sysupdate-required 2124-3000 error?
• "beach.hac.lp1.eshop.nintendo.net": Same result as dauth when blocked.
• "consumer.lp1.npns.srv.nintendo.net": Same result as dauth when blocked.
• "e0d67c509fb203858ebcb2fe3f88c2aa.baas.nintendo.com": Used to handle account metadata. (friends, profile, etc)
• "api.accounts.nintendo.com": Appears to be used by Nintendo apps to get metadata for Switch user profiles.
• "api-lp1.znc.srv.nintendo.net": Used by the Switch Online app to get app data, like the list of game-specific services to display.

Note: "break Nintendo-account..." is for "posting to social-media" in user-profile, results may vary with the eShop (for non-dauth).
