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.
