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 trybeforenetplan 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, andnetworksetupchanges 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 generatefor 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/interfaceson 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
nmcliwithout also settingipv4.method manual; with the method left atauto, DHCP keeps running and the static address is only added next to the leased one. - Assuming
Set-DnsClientServerAddresschanges name resolution globally; it is per interface, so other adapters (VPN, second NIC) keep their own servers. Check withGet-DnsClientServerAddress;-ResetServerAddressesreturns to DHCP-supplied servers.
