192.168.100.43 router login
To open the admin panel, type 192.168.100.43 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.
192.168.100.43 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 192.168.100.43. That is expected: the address is private space with no fixed device behind it, so credentials depend entirely on whatever hardware happens to hold it on your network. Any list claiming to know the login for this address is guessing.
Find the device first, then its own defaults. They are commonly printed on a sticker on the underside or rear panel, in the quick-start leaflet, or in the manufacturer's manual under the exact model number. If the unit came from an internet provider, the provider's own documentation or account portal often carries per-device credentials, and these are frequently unique to the serial number.
How to log in to your router
Type 192.168.100.43 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 192.168.100.43, 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 login is unknown, try the printed defaults first, then check whether a previous administrator recorded a changed password. Browsing to http://192.168.100.43 usually reveals the login page and often the device type, which narrows down where to look.
A factory reset is the last resort because it is not free. It clears the administrator password, but also the wireless network name and key, port forwarding, static leases, firewall rules and any provider-specific settings, so devices reconnect only after the network is rebuilt. The method varies by hardware; a recessed reset button held for several seconds while powered on is common, but confirm the timing in the manual for your model rather than assuming. Record the current configuration beforehand if the interface is still reachable.
192.168.100.43 is a private IPv4 address. It falls inside 192.168.0.0/16, the block RFC 1918 sets aside for private use alongside 10.0.0.0/8 and 172.16.0.0/12. That block holds 65,536 addresses under a 255.255.0.0 netmask and is the consumer range: nearly every home router, mobile hotspot and small office access point ships a default gateway somewhere inside it, which is why it is the range most people run into. Because the space is private, the address is not routable on the public internet and is not assigned to any organisation, provider or place. The same address is in use simultaneously on countless unrelated networks, and no registry records who holds it.
Within that block the address sits in the 192.168.100.0/24 subnet, which spans 192.168.100.1 through 192.168.100.254 with 192.168.100.255 reserved as the broadcast address. It is the 43rd host position, which is not one of the low positions routers commonly take for themselves. On a typical network that position is handed out by DHCP or set statically, so 192.168.100.43 is more often a client, printer, camera, NAS or access point than the gateway.
Most people arriving here have seen the address in a router's client list, a network scan or a device label and want to reach its configuration page, or to work out what it belongs to.

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.
