 **A:** You can generate a new private key and specific the first byte of its public key here:  https://gessaman.com/mc-keygen/
 
+Having multiple repeaters with the same first byte ID does not negatively affect the mesh or its functionality. Flood and pathed packets will still reach their destinations. First byte ID collision makes traceroute and path analysis harder because these tools don't know exactly which of the two (or more) colliding repeaters is the one in the path.
+
+Best practice is when you set up a new repeater, choose a public key that is not in use. If it is not possible to find a unique first byte for your repeater's public key, choose one that is unique within about 10 miles (16 km) to minimize collision with nearby repeaters.

+### 3.9. Q: What is multi-byte support?  What do 1-byte, 2-byte, 3-byte adverts and messages mean?
+
+**A:**
+The original MeshCore protocol design uses the first byte of a repeater's public key to denote the repeater in a path.  And with 1 byte for each repeater in the path, MeshCore packets can travel as many as 64 hops.  
+
+However, with 1 byte, there are only 254 unique IDs (exclude 00 and FF which are reserved).  Many meshes group have multiple repeaters with the same first byte in their public keys. Packets continue to pass through repeaters and the mesh is not harmed in anyway.  It does make it harder for tools to analyze paths with duplicated repeater IDs.  
+
+Firmware version 1.14 and newer introduces the ability for repeaters to advert with 1-, 2-, or 3-byte adverts.  Companions can also send out channel and direct messages with 1-, 2-, or 3-byte path.  Adverts and messages sent in 1-byte path is compatible with repeater firmware older or newer than 1.14.  They will travel up to 64 hops.  2-byte adverts and messages will travel up to 32 hops.  3-byte adverts and messages will travel up to 21 hops.
+
+### 3.9.1. Q: **What path hash sizes will my repeater forward?**
+
+Repeaters running firmware 1.14+ repeat packets sent with 1-, 2-, or 3-byte path hash. Repeaters on firmware older than 1.14 only repeat 1-byte path hash packets and silently drop 2- and 3-byte packets.
+
+### 3.9.2. Q: **What determines a packet's path hash size?**
+
+The original packet sender determines the path hash size. The most common original sender is a companion app. The other common original sender is a repeater, when it broadcasts its advert.
+
+### 3.9.3. Q: **How do I change my companion's path hash size?**
+
+As of firmware version 1.14 and MeshCore app version 1.41.0, in the MeshCore app, you can set your companion's message path hash size in `Settings (gear icon)`, `Experimental Settings`. 
+
+Until your regional mesh has the vast majority of the repeaters updated to 1.14+ firmware, it is recommended to keep your companion at the default 1-byte because pre-1.14 repeaters will silently drop messages with larger path hashes.
+
+### 3.9.4. Q: **What does the CLI command `path.hash.mode` do on a repeater?**
+
+This CLI command `path.hash.mode` *only* controls the path hash size used in a repeater's own advert broadcasts. It does **NOT** affect which packets the repeater forwards. A repeater with firmware 1.14+ always forward 1-, 2-, and 3-byte packets regardless of this setting.
+
+Usage: `set path.hash.mode {0|1|2}`:
+
+```
+┌────────────────┬───────────────────────┐
+│ path.hash.mode │ Advert path hash size │
+├────────────────┼───────────────────────┤
+│ 0              │ 1 byte (default)      │
+├────────────────┼───────────────────────┤
+│ 1              │ 2 bytes               │
+├────────────────┼───────────────────────┤
+│ 2              │ 3 bytes               │
+└────────────────┴───────────────────────┘  
+```
+
+It is safe to set your 1.14+ repeaters to mode 1 or 2.
+
+### 3.9.5. Q: **Why use 2- or 3-byte path hash for adverts?**
+
+A longer path hash helps tools like the LetsMesh.net Analyzer and MeshMapper disambiguate repeaters more reliably. With only 1 byte, the chance of different repeaters having the same first byte in their public key is high, making it harder to tell them apart in mesh network analysis. Since this only affects adverts, there's no downside.  2- and 3-byte adverts don't travel as far as 1-byte adverts, but it is not important for MeshCore nodes to hear a repeater's advert that are 21 or 32 hops away.
+
+### 3.9.6. Q: **When can we move away from 1-byte path hash for channel and direct messages?**
+
+You should move to send 2-byte or 3-byte channel and direct messages when the vast majority of the repeaters in your regional mesh are updated to firmware version 1.14 or newer.  Setting your repeater's `path.hash.mode` to 1 (for 2-byte path hash) or 2 (for 3-byte path hash) now helps the community gauge to how many repeaters have updated to 1.14+.  Please work with your MeshCore community together to decide when to switch to 2-byte path or 3-byte path for channel and direct messages.
