10.100.1.2 router login
To open the admin panel, type 10.100.1.2 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.
10.100.1.2 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.
There are no documented default username and password pairs for 10.100.1.2. That is expected rather than a gap: credentials belong to a device, not to an address, and since no vendor is known to ship this address as a default, there is no defensible pair to publish. Any site that lists one for 10.100.1.2 is guessing.
Find the real defaults on the device itself. Check the label or sticker on its underside or rear panel, which on many devices prints the default address, username, password or Wi-Fi key. Failing that, consult the printed or PDF manual for the exact model number, or your ISP's documentation if the equipment was supplied with a service, since ISPs frequently set per-unit credentials that differ from the manufacturer's.
How to log in to your router
Type 10.100.1.2 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 10.100.1.2, 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 device at 10.100.1.2 rejects every credential you have, the general recovery path is a factory reset: with the unit powered on, hold the recessed reset button, usually pressed with a paperclip, for roughly 10 to 30 seconds until the status lights cycle, then wait for the device to reboot. The exact hold time and button location vary by model, so confirm against that model's manual before committing.
Understand the cost first. A reset commonly erases Wi-Fi names and passwords, port forwards, firewall and VLAN rules, static leases, VPN profiles and any ISP-specific provisioning. On a network using 10.100.1.0/24 the addressing itself is often custom, so the device may come back on a different default subnet and stop answering at 10.100.1.2 at all. Export a configuration backup beforehand if the interface still permits it, and check with whoever administers the network before resetting shared equipment.
Troubleshooting 10.100.1.2
Confirm 10.100.1.2 exists on your network
Because 10.0.0.0/8 is private and reused everywhere, 10.100.1.2 is only reachable if your own machine is on the 10.100.1.0/24 segment or is routed to it. Check your own address first: on Windows run ipconfig /all, on Linux run ip addr, on macOS open the network settings pane. If your address is 192.168.x.x or 172.16-31.x.x, you are on a different network entirely and this address will never answer.
Find the actual gateway on this network
10.100.1.2 is the second usable host in its /24, not the conventional .1 gateway position, so it may not be your router at all. On Windows, ipconfig /all and read Default Gateway. On Linux, ip route and read the default via line. On macOS, open the network settings pane and check the Router field under TCP/IP details. Whatever address appears there is the device to log into.
Try HTTP and HTTPS before assuming failure
Type http://10.100.1.2 explicitly. Many browsers now assume HTTPS and will fail against a device that only serves plain HTTP, or show a certificate warning on one that serves HTTPS with a self-signed certificate, which is normal for local equipment. If neither responds, try a non-standard management port such as http://10.100.1.2:8080 or https://10.100.1.2:8443, both common on secondary and management interfaces.
Check for a typo in the address
Enter the address into the URL bar, not a search box, or the browser will run a web search instead. Watch for the common slips: 10.100.1.2 written as 10.100.l.2 with a letter l, extra digits such as 10.100.1.22, a stray www prefix, or a trailing dot. There is no domain suffix to add and no https requirement, so keep it to the four numeric octets.
Reach the device when nothing responds
Ping 10.100.1.2 from a command prompt or terminal. Replies with no web page usually mean the management interface is on another port or restricted to a specific interface or VLAN. No replies at all suggest the address is unused, the device is off, or a firewall or client-isolation feature is blocking you. Connecting by Ethernet cable directly to the device bypasses most wireless isolation rules.
Login page loads but rejects credentials
Repeated rejection usually means the password was changed from the factory default, which is standard practice on equipment sitting inside a 10.0.0.0/8 corporate or campus network. Check the device label and its manual for the model's own defaults, watch for caps lock and locale-specific keyboard layouts, and clear cached credentials or try a private browsing window. Many devices lock out for several minutes after a handful of failures, so pause between attempts.
Questions about 10.100.1.2
Is 10.100.1.2 a router address?
It can be, but it is not the typical position for one. It is the second usable address in 10.100.1.0/24, and administrators conventionally assign the gateway to the first, 10.100.1.1. An address at the .2 position more often belongs to a secondary router, an access point, a firewall or server management interface, or an early DHCP lease. Check your machine's default gateway to see what your network actually uses.
Which router brand uses 10.100.1.2 by default?
No specific vendor is known to ship 10.100.1.2 as a default gateway address. Addresses in 10.0.0.0/8 are usually assigned by whoever designed the network rather than preset at the factory, so the device answering here was almost certainly configured deliberately. Identify it by its physical label or model number rather than by the address, since the address alone reveals nothing about the manufacturer.
Where is 10.100.1.2 located, and who owns it?
Nowhere and no one. 10.0.0.0/8 is private space reserved by RFC 1918 and is never routed on the public internet, so it has no registrant, no ISP, no organisation and no geographic location. The same address is in use on a great many unrelated networks at the same time. Any lookup claiming a city or provider for it is reporting something else, such as your public address.
What is the default password for 10.100.1.2?
There is no published default for this address, and no honest source can supply one, because passwords belong to devices rather than to addresses. Look on the sticker on the device's underside or rear panel, in the manual for that exact model, or in your ISP's paperwork if the hardware came with a service. On managed corporate or campus networks, the credentials are usually held by whoever administers the network.
Why can I reach 10.100.1.2 at work but not at home?
Because private addresses are only meaningful inside the network that uses them. The 10.100.1.0/24 subnet exists on that particular network, and your home network almost certainly uses different addressing, commonly 192.168.x.x. Nothing at home routes toward 10.100.1.2, so the request simply fails. Reaching it remotely requires a VPN into the network that hosts the subnet, which is a common use of 10.0.0.0/8 address pools.
How many addresses are in this subnet and this block?
The 10.0.0.0/8 block holds 16,777,216 addresses in total, which is why it is favoured by large corporate, campus and carrier deployments. In practice it is subnetted far smaller. Here it is divided into 10.100.1.0/24, whose usable hosts run from 10.100.1.1 through 10.100.1.254, with 10.100.1.255 reserved as the broadcast address. Four other addresses in this same /24 are documented separately.
Should I change the device from 10.100.1.2?
Only if you understand the segment's addressing plan. On networks built from 10.0.0.0/8, addresses are often allocated deliberately, and a device at 10.100.1.2 may be referenced by static routes, firewall rules, port forwards, DHCP reservations or monitoring systems. Changing it can break those silently. If the address was assigned by DHCP and you need it stable, create a reservation rather than editing the device's own configuration.
10.100.1.2 is a private IPv4 address drawn from 10.0.0.0/8, the largest of the three blocks reserved for private use by RFC 1918. With a netmask of 255.0.0.0, that block spans 16,777,216 addresses, and it is the space most often chosen by corporate and campus networks, ISP-managed CPE, carrier-grade equipment, VPN address pools, and container or orchestration networks. In practice almost nobody routes a flat /8; the space is subnetted far below that, which is how an address like 10.100.1.2 comes to exist inside a much smaller segment. Because the block is private, the same address is in simultaneous use on countless unrelated networks, and it carries no location, owner, ISP or registrant of any kind.
Within its own segment, 10.100.1.2 sits in the 10.100.1.0/24 subnet, where usable host addresses run from 10.100.1.1 to 10.100.1.254 and 10.100.1.255 is the broadcast address. It is the second usable address in that range, not the first. That distinction matters: administrators commonly place the gateway at the .1 position, so 10.100.1.2 is more often a device sitting beside the gateway than the gateway itself. It is a plausible address for a secondary router, a firewall or access point, a management interface, a DHCP or DNS server, a NAS, or simply an early DHCP lease. Four other addresses in this same /24 are documented separately.
No specific router vendor is known to ship 10.100.1.2 as a default gateway address, so nothing here should be read as identifying a brand or model. Most of the roughly 851 people a year who look this address up are trying to open a login page they saw in a configuration screen, a lease table, or a colleague's notes, and want to know what is likely listening there and how to get in.
