172.17.2.1 router login
To open the admin panel, type 172.17.2.1 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.
172.17.2.1 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 on record for 172.17.2.1, and guessing at one would be useless. 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 manufacturer's manual. Equipment supplied by an ISP often has credentials listed in the service documentation instead.
How to log in to your router
Type 172.17.2.1 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 172.17.2.1, 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 nobody knows the password, look for a recessed reset button and hold it while the unit is powered, usually for ten to thirty seconds. Understand the cost first: a factory reset erases every custom setting, including port forwards, DHCP reservations and any firewall rules, and returns the Wi-Fi name and key to whatever is printed on the label. Save a configuration backup beforehand if you can still log in.
172.17.2.1 belongs to 172.16.0.0/12, the middle of the three ranges RFC 1918 sets aside for private use. With a 255.240.0.0 mask it covers 1,048,576 addresses, running from 172.16.0.0 up to 172.31.255.255. The boundaries trip people up: 172.15 and 172.32 are ordinary routable space, so only the sixteen /16s in between are private. Addresses here surface mainly in business LANs, lab builds, VPN subnets and container bridge networks.
Locally the address falls inside 172.17.2.0/24, where usable hosts run 172.17.2.1 through 172.17.2.254 and 172.17.2.255 is the broadcast address. It holds the first usable slot, the position administrators most often hand to a router or firewall interface, and nine further addresses in that same /24 are documented here. Visitors typically arrive wanting to open a management page on it or identify what is answering.

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.
Comment:
Comment: These addresses can be used by anyone without any need to coordinate with IANA or an Internet registry. The traffic from these addresses does not come from ICANN or IANA.
