10.100.1.1 is a private IPv4 address inside 10.0.0.0/8, the largest of the three RFC 1918 ranges. With a netmask of 255.0.0.0 the block spans 16,777,216 addresses, and none of them are routable across the public internet. That size is the reason 10.0.0.0/8 turns up in corporate and campus networks, ISP-managed customer equipment, carrier-grade gear, VPN address pools and container or orchestration networks, where it is almost always subnetted far below /8. Because the space is unallocated and reusable, the same address exists at the same moment on countless unrelated networks, and it has no owner, operator or location of its own.
On this page the address is treated as part of 10.100.1.0/24, a 254-host subnet whose usable range is 10.100.1.1 to 10.100.1.254 and whose broadcast address is 10.100.1.255. 10.100.1.1 is the first usable host in that range, the position routers and firewalls are commonly configured to take, which is why it frequently acts as a default gateway rather than as a client address. Four other addresses in the same /24 are documented separately, a pattern typical of a subnet with infrastructure at the low end and DHCP clients above it.
The one vendor known to ship this address as a default gateway is Vodafone, on its Station series routers. Other equipment can end up on it too, since any administrator can assign 10.100.1.1 to an interface, but no other make or model is documented here as arriving with it preset. Most people who look the address up are trying to open its web administration page in a browser: to change a Wi-Fi name or passphrase, set up port forwarding, see which devices are connected, or work out whether 10.100.1.1 is really the gateway on the network they are attached to.
To open the admin panel, type 10.100.1.1 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. http://10.100.1.1
We hold no reported default credentials for 10.100.1.1. That is not a gap to fill with a guess: no vendor is documented as shipping this address as a factory default, so any list published for it would be invented. The credentials you need belong to whichever device holds this address on your own network.
Where to find them:
No default username and password pair is recorded for 10.100.1.1, and guessing at one would not help: sign-in details belong to a particular device, not to an address that many different makes of equipment can share. Look first at the label on the underside or rear of the router, where the administration user name and password are commonly printed alongside the Wi-Fi details; on recent provider-supplied units that password is usually unique per device rather than a shared factory value.
If the label is missing or worn, check the quick-start card that came in the box, the manufacturer's manual for your exact model number, or, for equipment supplied and managed by an internet provider, the account paperwork or support pages for that service. Whoever installed the device may also have set a password of their own, in which case no printed default will work.
| Vendor | Models | Username / Password |
|---|---|---|
| Vodafone | Station series | vodafone / vodafone |
If the administration password has been changed and cannot be recovered, a factory reset is the only dependable way back in. Vodafone Station hardware uses a recessed pinhole reset: with the unit powered on, hold the button in with a straightened paperclip for roughly ten seconds, until the indicator lights change, then let the router restart on its own without cutting power.
The cost of that is real. A reset returns the Wi-Fi network name and passphrase to whatever the label shows, so every phone, laptop and smart-home device has to be reconnected, and it also discards port forwards, static DHCP reservations, custom DNS settings, firewall rules and parental controls. Provider-managed units often pull part of their configuration back automatically after they reconnect, but anything configured locally is gone.
Reset method by vendor:
Type 10.100.1.1 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 10.100.1.1, 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.
Confirm the computer is joined to the network the router serves, not a guest SSID, a neighbouring network or a mobile hotspot. Guest networks are commonly isolated from the management interface by design. Then test reachability with ping 10.100.1.1 before blaming the browser: if the ping fails, the problem is the network path, not the web page.
On Windows run ipconfig /all in Command Prompt and read the Default Gateway line for your active adapter. On Linux run ip route and look at the address after "default via". On macOS open System Settings, Network, select the active connection, then Details and TCP/IP, and read the Router field. If it shows a different address, browse to that one instead.
Corporate VPN clients frequently push a route for the whole of 10.0.0.0/8, so traffic to 10.100.1.1 is sent down the tunnel rather than to the router in front of you. The symptom is a page that times out only while the VPN is connected. Disconnect the VPN, or check its split-tunnel configuration, then retry the address.
Type http://10.100.1.1 in full. Left to itself a browser may treat a bare address as a search term or force an HTTPS attempt the device cannot answer. Some units listen on 8080 or 8443 instead, reachable as http://10.100.1.1:8080. Certificate warnings are normal on private addresses, because no public authority issues certificates for RFC 1918 space.
There is no www prefix and no domain suffix; 10.100.1.1.com or www.10.100.1.1 will not resolve. Watch for near misses such as 10.100.11.1, 10.100.1.11, 10.10.0.1 and 10.1.100.1, all of them valid private addresses that may belong to something else entirely on a network using 10.0.0.0/8. Clear the address bar completely before retyping.
Check caps lock and any autofilled entry left over from a different router. Then compare what you are typing against the label on the device itself, since many provider-supplied units carry a per-device password rather than a shared one. Repeated failures can trigger a lockout of several minutes on some firmware, so pause rather than retrying in quick succession.
10.100.1.1 is often mistyped. These all refer to the same address:
l0.l00.l.l, 1o.1oo.1.1, 10.100..1.1, 10 100 1 1, 10.100.1.1..
The most common slip is typing a lower-case letter L in place of the digit 1, or the letter O in place of a zero.
The 10.100.1.0/24 subnet runs from 10.100.1.1 to 10.100.1.254, with 10.100.1.255 reserved as the broadcast address. These are the addresses in it we hold router login details for.
