- Network ID
- The network's globally unique 16-digit ID. This cannot currently be changed.
- Name
- A user-defined short name for this network that is visible to members. We recommend using
something
like a domain name (e.g. zerotier.com) or e-mail address.
- Description
- A longer description of this network.
- Access Control
- How is membership controlled? This should be left on its default Certificate setting unless you
want
to create a totally open network for testing, gaming, etc.
- Multicast Recipient Limit
- The maximum number of recipients that can receive an Ethernet multicast or broadcast. If the
number
of recipients exceeds this limit, a random subset will receive the announcement. Setting this higher
makes multicasts more reliable on large networks at the expense of bandwidth. Setting to 0 disables
multicast, but be aware that only IPv6 with NDP emulation (RFC4193 or 6PLANE addressing modes) or
other unicast-only protocols will work without multicast.
- Managed Routes
- IPv4 and IPv6 routes to be published to network members. This can be used to create routes to
other
networks via gateways on a ZeroTier network. Note that for security reasons most clients will not
use
default routes or routes that overlap with public IP address space unless this is specifically
allowed
by the user. Public IP ranges are marked with an icon.
- IPv4 Auto-Assign
- IPv4 range from which to auto-assign IPs. Note that IPs will only be assigned if they also fall
within
a defined route. Easy mode allows users to pick an IP range and a route and pool definition will
automatically be created.
- IPv6 Auto-Assign
- IPv6 addresses can be automatically assigned with the RFC4193 or 6PLANE addressing schemes, or
from a
user-defined IPv6 range.
- IPv6 Auto-Assign Details
- RFC4193 assigns each device a single IPv6 /128 address computed from the
network ID and device address, and uses NDP emulation to make these addresses instantly resolvable
without multicast.
- IPv6 Auto-Assign Details
- 6PLANE assigns each device a single IPv6 address within a fully routable /80
block and uses NDP emulation to “magically” route the entire /80 to its owner, allowing each device
to
assign up to 2^48 IPs without additional configuration. This is designed for use with Docker or on
VM
hosts.
- IPv6 Auto-Assign Details
- Range assigns each device an IP from a user-defined IPv6 range. An example
might
look like: “2001:abcd:ef00::” to “2001:abcd:ef00:ffff:ffff:ffff:ffff:ffff”.
- DNS Push
- Requires ZeroTier version 1.6. Older versions of ZeroTier will ignore these settings.
- DNS Push Details
- On macOS, iOS, Windows, and Android, ZeroTier can automatically add DNS
servers
for a specific domain. It does not set up or host a DNS server. You must host your own.
- DNS Push Example
- If you configure zt.example.com as your search domain, and 10.147.20.1 as a
server address, then your computer will ask 10.147.20.1 to look up IP addresses for hostnames ending
in zt.example.com.
- DNS Push Enablement
- This must be enabled on each client with the allowDNS option. There is a
checkbox
in the UI in each network's details, near the Allow Managed checkbox.
