What is IP Lock vs Multi-Device Connections?
Protocol Definition & Architecture: Definition And Guide
Technical Definition
IP lock restricts a subscription line to a single public IP address, while max_connections limits simultaneous streams regardless of IP. Panels expose both so resellers can sell household lines (2-5 connections) or locked single-device lines.
How It Operates Under the Hood
With IP lock, a stream request from a new IP returns 403 until the lock is cleared or the previous session ends; VPN exit changes trigger this. max_connections counts active sessions (active_cons) and rejects the N+1th stream with 403 / 458.
Beginner to Engineer Guide
IP Lock vs Multi-Device Connections matters to subscribers because it directly affects how quickly a channel starts, how stable it stays, and how the guide and catch-up behave. For resellers it determines which players and devices to recommend and which panel settings to expose.

IP Lock vs Multi-Device Connections FAQ
What is IP Lock vs Multi-Device Connections in simple terms?
IP lock restricts a subscription line to a single public IP address, while max_connections limits simultaneous streams regardless of IP. Panels expose both so resellers can sell household lines (2-5 connections) or locked single-device lines.
Why does my stream stop when I enable a VPN?
The exit IP changed and the line is IP-locked; ask the reseller to disable the lock or keep one VPN server.
What is the difference between Xtream Codes API, M3U URL, and Stalker Portal login?
All three deliver the same channels. Xtream Codes API uses player_api.php JSON endpoints so the player lazy-loads categories and EPG in seconds. An M3U URL (get.php) downloads a single text playlist of every stream, which is slow with 45,000 channels but works on any player. Stalker Portal authenticates by MAC address through a /c/ portal URL and is used by MAG receivers and some Smart TV apps.
Why is my EPG guide empty or showing programs at the wrong time?
Players fetch an XMLTV file from xmltv.php and match each channel by tvg-id. An empty guide means the player downloaded the file before the server finished its 15-minute refresh or the file exceeded the player size cap (set TiviMate EPG update to "never limit"). Wrong times are a timezone offset issue: XMLTV timestamps carry +0000 and the player must apply your local offset, so set an EPG shift of +1 or -5 hours in the channel settings rather than changing the device clock.
How far behind live are IPTV sports streams and can latency be reduced?
Standard HLS with 4-second segments and a 3-segment player window sits 12-18 seconds behind the broadcast. Low-Latency HLS with 0.5-second partial segments brings glass-to-glass delay to about 3.8 seconds, and raw MPEG-TS over HTTP (.ts output format) is typically 5-7 seconds behind. Choose the .ts output format in your player for live sports and reserve .m3u8 for VOD and catch-up.
What buffer size should I set in TiviMate, Smarters, or XCIPTV for 4K sports?
Set the largest option (5,000 ms in TiviMate, "Large" in Smarters). Buffer time in seconds equals buffer bytes multiplied by 8, divided by the stream bitrate in Mbps: a 15 MB allocation on an 18.5 Mbps 4K feed yields 6.5 seconds of protection, which covers typical ISP shaping bursts of 2-4 seconds without a visible freeze.
Do providers offer a free trial and how long does activation take?
Every network in this directory issues 24-hour trial lines from the reseller panel. Activation is instant: the panel writes the line to the Xtream database and the player can authenticate within 10 seconds. Trial lines are usually limited to 1 connection and exclude PPV bouquets.
