# Network configuration tools compared: nmcli, netplan, systemd-networkd and their Windows and macOS equivalents

Reading the current network configuration, setting a static address, and setting DNS servers — the same three tasks across NetworkManager's nmcli, Ubuntu's netplan, systemd-networkd, Windows PowerShell's networking cmdlets, and macOS's networksetup.

## What it is
| Task | NetworkManager (nmcli) | Ubuntu netplan | systemd-networkd | ifupdown | Windows | macOS | FreeBSD |
|---|---|---|---|---|---|---|---|
| Read current config | `nmcli connection show NAME` | inspect the YAML under `/etc/netplan/`, or `netplan get` | `networkctl status IFACE` | read `/etc/network/interfaces` | `Get-NetIPConfiguration` | `networksetup -getinfo "Wi-Fi"` (or the relevant service name) | read `/etc/rc.conf`'s `ifconfig_IFACE` lines |
| Set a static address | `nmcli connection modify NAME ipv4.addresses 192.0.2.10/24 ipv4.gateway 192.0.2.1 ipv4.method manual`, then `nmcli connection up NAME` to apply | edit the YAML (`addresses:` under the interface, `dhcp4: false`), then `netplan apply` | edit a `.network` file's `[Network]`/`[Address]` sections, then `networkctl reload` (systemd 244 and later) or restart `systemd-networkd` | edit the `iface IFACE inet static` block in `/etc/network/interfaces`; applied by `ifdown`/`ifup` of that interface | `New-NetIPAddress -InterfaceAlias NAME -IPAddress 192.0.2.10 -PrefixLength 24 -DefaultGateway 192.0.2.1` (takes effect immediately) | `networksetup -setmanual "Wi-Fi" 192.0.2.10 255.255.255.0 192.0.2.1` | `sysrc ifconfig_IFACE="inet 192.0.2.10 netmask 255.255.255.0"`, then `service netif restart IFACE` |
| Set DNS servers | `nmcli connection modify NAME ipv4.dns "1.1.1.1 9.9.9.9"` (add `ipv4.ignore-auto-dns yes` to drop DHCP-supplied servers) | add `nameservers: {addresses: [...]}` to the YAML | set `DNS=` in the `.network` file's `[Network]` section | add a `dns-nameservers` line to the interface stanza (needs the `resolvconf` package) | `Set-DnsClientServerAddress -InterfaceAlias NAME -ServerAddresses 1.1.1.1,9.9.9.9` | `networksetup -setdnsservers "Wi-Fi" 1.1.1.1 9.9.9.9` | set `resolv.conf` directly, or via DHCP client configuration |

## Why it matters
Two mistakes recur across all of these: forgetting to *apply* a staged change (`netplan apply`, `nmcli connection up`, `networkctl reload`), and applying a change over the very connection used to reach the host, cutting the session before the command finishes. A YAML or config-file-based tool (netplan, ifupdown, FreeBSD's rc.conf, systemd-networkd) also has a syntax-validity gap that `nmcli` and the PowerShell cmdlets do not: a malformed file may not error until the service tries to reload it, sometimes at the next boot.

## How to apply
- On netplan, run `netplan try` before `netplan apply`; it reverts automatically unless confirmed within 120 seconds, protecting against a lockout. The Linux, FreeBSD and Windows commands need root or an elevated shell, and `networksetup` changes need admin rights.
- On any file-based tool, keep a copy of the working configuration before editing, and validate syntax (where a validator exists, e.g. `netplan generate` for a dry parse) before applying.
- Confirm a change from the running state (`ip addr`, `resolvectl status`, `ifconfig`, `Get-NetIPConfiguration`), not by re-reading the file you edited.
- Change one property at a time (address, then DNS), especially on hosts reached only over the network you are reconfiguring.

## Pitfalls
- Editing `/etc/network/interfaces` on Ubuntu 17.10 or later, which uses netplan; unless ifupdown was installed deliberately, the file is ignored and the change has no effect.
- Setting a static address with `nmcli` without also setting `ipv4.method manual`; with the method left at `auto`, DHCP keeps running and the static address is only added next to the leased one.
- Assuming `Set-DnsClientServerAddress` changes name resolution globally; it is per interface, so other adapters (VPN, second NIC) keep their own servers. Check with `Get-DnsClientServerAddress`; `-ResetServerAddresses` returns to DHCP-supplied servers.
