172.16.189.4 router login
To open the admin panel, type 172.16.189.4 into your browser's address bar. If the page does not load, this is probably not the gateway address on your network — see the checks below.
172.16.189.4 router passwords
Where to find them:
- The label on the underside or back of the router — most manufacturers print the default admin username, password and Wi-Fi key there.
- The quick-start card or manual that came in the box.
- Your ISP's account portal, if the device was supplied by them — many set a unique password per line rather than a shared default.
No default username and password pair is documented for anything answering on 172.16.189.4, and guessing one would be a waste of attempts. Whatever device holds this address prints or ships its own defaults: check the label on the underside or rear panel, the quick-start card in the box, or the administrator documentation supplied with the appliance or the network it belongs to.
How to log in to your router
Type 172.16.189.4 into your browser's address bar and press Enter. Type it by hand rather than accepting an autocomplete suggestion, which often fills in a different address you visited before.
If the browser reports that it cannot reach 172.16.189.4, this is not the gateway address on your network. On Windows run ipconfig /all and read the Default Gateway line; on macOS open System Settings, Network, Details, TCP/IP; on Linux run ip route and read the address after "default via".
If the login page loads but rejects your credentials, and you have never changed them, use the defaults printed on the device's label. If they have been changed and nobody knows the new password, a factory reset is the only way back in.
If you do not know the password
If the credentials are genuinely lost, a factory reset is the usual fallback, normally a recessed button held for roughly ten to thirty seconds while powered. Treat it as a last step. The reset wipes port forwards, static leases, firewall rules and any VLAN work, and returns the Wi-Fi name and passphrase to the values printed on the label, so every connected client must be rejoined.
172.16.189.4 sits inside 172.16.0.0/12, the mid-size private range that runs from 172.16.x.x to 172.31.x.x and covers 1,048,576 addresses under the netmask 255.240.0.0. That block turns up mostly in business networks, lab builds, VPN subnets and container bridge networks rather than in home broadband. It is also the range most often mistaken for public space, because 172 addresses outside the 16-to-31 band really are routable on the internet.
The surrounding segment, 172.16.189.0/24, offers hosts from 172.16.189.1 to 172.16.189.254 with 172.16.189.255 reserved for broadcast. Position 4 is low in that range but is not a conventional gateway slot; it reads more like a statically assigned server, hypervisor or appliance. Most people arriving here have seen the address in an ARP table, a route print or a container inspect output and want to know what is answering on it.

Comment: These addresses are in use by many millions of independently operated networks, which might be as small as a single computer connected to a home gateway, and are automatically configured in hundreds of millions of devices. They are only intended for use within a private context and traffic that needs to cross the Internet will need to use a different, unique address.
