172.20.64.4 router login
To open the admin panel, type 172.20.64.4 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.
172.20.64.4 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 credentials are recorded for this address, and on a network numbered this deliberately the administrative accounts have very likely been changed from whatever the hardware shipped with. Guessing is doubly pointless here.
If the device is yours to administer, the shipped defaults are normally on the asset label, in the model's manual, or in the vendor's online documentation for that exact part number. If the equipment belongs to an employer, a campus or a client, the working credentials will sit in that organisation's password vault or configuration management system rather than on a sticker.
How to log in to your router
Type 172.20.64.4 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 172.20.64.4, 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
Factory resetting managed or business-class equipment is a heavier decision than resetting a home router. The reset clears routing and VLAN configuration, access control lists, VPN tunnels, certificates, licences in some cases, and logging destinations, and it usually drops every service the device carries until an engineer restores a saved configuration.
Since no vendor is documented for this address, use the recovery procedure for the actual model. Many enterprise devices support console access with a password recovery sequence at boot, which preserves the configuration and is far preferable to a full erase. Confirm a current backup exists before touching anything.
172.20.64.4 falls within 172.16.0.0/12, the mid-size private block that runs from 172.16.x.x through 172.31.x.x and covers 1,048,576 addresses under a 255.240.0.0 netmask. This range causes more confusion than the others because 172.x.x.x addresses outside the 172.16 to 172.31 window are ordinary public space. Inside the window the addresses are private and reusable, which rules out any claim about an owner, an operator or a geographic origin.
Addresses in this block turn up most often in mid-size business networks, laboratory and test environments, VPN address pools and container platforms, where the /12 is carved into far smaller subnets. The segment here is 172.20.64.0/24, with usable addresses from 172.20.64.1 to 172.20.64.254 and broadcast at 172.20.64.255. A third octet of 64 suggests a deliberately structured addressing plan rather than an out-of-the-box default, since consumer equipment almost never ships with numbering like this.
Position 4 is a low slot, typically reserved by hand for infrastructure sitting alongside the gateway rather than for the gateway itself. Only one other address in this /24 has been documented, which fits a managed network that is not publicly described. Visitors are usually mapping an unfamiliar internal address.

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.
