This page documents DNS domains and lists information relevant to the online services used by the Switch.

Domains

Only HTTPS is used with these domains unless noted otherwise.

CDN

The URLs for content delivery network servers on the Switch usually follow this format:

{server_name}.hac.{environment}.{serverset}.nintendo.net

Where:

{server_name}: One of the registered server names.
{environment}: "dp1", "lp1", "sp1", "dd1", "jd1", "sd1", "td1" or "xd1".
{serverset}: "eshop" (online shop) or "d4c" (content delivery).

Servers

sun

Used for checking whether a sysupdate is available. Equivalent to NetUpdateSOAP from past systems.

NIM sends a HTTP GET with the sun URL to get the title-listing of the latest system-titles, as .json. The deviceid in the URL is the same one in the above User-Agent section. HTTP header "Accept:application/json" is sent in the request.

The response is json with a "system_update_metas" block, containing "title_id" and "title_version" entries. The actual server response only contains 1 title.

Example, from 2.0 system:

{"timestamp":REDACTED-TIMESTSAMP,"system_update_metas":[{"title_id":"0100000000000816","title_version":201327002}]}

URLs:

"https://sun.hac.%%.d4c.nintendo.net/v1/system_update_meta?device_id=%016llx"

aqua

The following response is json from accessing the aqua URL:

{ "contents_delivery_required_title_id": "0100000000000816", "contents_delivery_required_title_version": 0 }

A while after 3.0.0 release, the above title-version was changed to the one for v3.0("Last-Modified: Thu, 29 Jun 2017 00:00:04 GMT").

URLs:

"https://aqua.hac.%%.d4c.nintendo.net/required_system_update_meta?device_id=%016llx"

atum/atumn

CDN for system-titles.

While "atumn" seems to be for system-titles and "atum" for eShop titles, the latter titles are accessible fine with atumn (with "/t/" for NCA-type0 at least).

'a' is used when an input u8 is not 0x3, otherwise 's' is used. A seperate function using the ".../c/" URL is hard-coded to use 'c'. This appears to match 's' usage attempts: the only URL that returned actual data with 's' was with titleID 0100000000000816.

As of June 30, 2017, accessing old content via the atumn "/c/" and "/t/" URLs works fine.

URLs:

"https://%s.hac.%%.d4c.nintendo.net/t/%c/%016llx/%u?device_id=%016llx"
Returns content like the below URL. First %s is atumn or atum. This is the content for NCA-type0. See below for %c. %016llx is titleID, %u is title-version.

"https://%s.hac.%%.d4c.nintendo.net/c/%c/%s"
Used for downloading content. First %s is atumn or atum. %c is one of: 'c', 'a', or 's'. %s is just the hex-string NcaId. The server also returns two HTTP headers: "X-Nintendo-Content-Hash: {entire lowercase hex-string of the content SHA256 hash}" and "X-Nintendo-Content-ID: {lowercase hex-string for NcaId}"

superfly

URLs:

"https://superfly.hac.%%.d4c.nintendo.net/v1/t/%016llx/dv"
%016llx is titleID, only for eShop titles it appears. Returns .json title-info.

"https://superfly.hac.%%.d4c.nintendo.net/v1/a/%016llx/dv"
%016llx is titleID, only for eShop titles it appears. Output is similar to above URL.

tagaya

VersionList for eShop titles.

URLs:

"https://tagaya.hac.%.eshop.nintendo.net/tagaya/hac_versionlist"

beach

URLs:

"https://beach.hac.%.eshop.nintendo.net/v1/rom_cards?application_id=%016llx&rom_card_cert=%s"
"https://beach.hac.%.eshop.nintendo.net/v1/rom_cards/register?application_id=%016llx&rom_card_cert=%s&expected_gold_point=%d"

Services

The URLs for general online service servers on the Switch usually follow one of these formats:

{server_name}-{environment}.{service_name}.srv.nintendo.net

Where:

{server_name}: One of the registered server names.
{environment}: "lp1" (production), "dd1" (development) or "sp1" (production lottest staging).
{service_name}: One of the various service names.

znc

Used by the Switch Online app to get app data, like the list of game-specific services to display.

Others

Miscellaneous domains for various APIs and tests.

Servers

Account metadata:

  • "e0d67c509fb203858ebcb2fe3f88c2aa.baas.nintendo.com"
  • "api.accounts.nintendo.com"

News and game content:

  • "bcat-topics-%.cdn.nintendo.net"
  • "bcat-list-%.cdn.nintendo.net"
  • "service-status-%.cdn.nintendo.net"
  • "g<game_server_id>-%.s.n.srv.nintendo.net"

Connection:

  • "ctest.cdn.nintendo.net" (replaces "conntest.nintendowifi.net")
  • "nasc.nintendowifi.net"

User-Agent

NIM generates two User-Agent strings:

snprintf(..., "User-Agent: NintendoSDK Firmware/%s-%u (platform:%s; did:%016llx; eid:%s)", <string at sysver+0x68>, {u32 from sysver+4}, "NX", DeviceId, {GetEnvironmentIdentifier output});
 
snprintf(..., "User-Agent: NintendoSDK Firmware/%s-%u (platform:%s; eid:%s)", <string at sysver+0x68>, {u32 from sysver+4}, "NX", DeviceId, {GetEnvironmentIdentifier output});

Where the 64bit DeviceId is parsed from the 0x10-bytes at outbuf+0xC6 from set:cal GetEciDeviceCertificate (DeviceCert_certname+2, aka where the hex string for the DeviceId is).
