10.0.0.138 router login

Because 10.0.0.138 is not a typical gateway position, verify before assuming. On Windows run ipconfig /all and read the Default Gateway line for your active adapter. On Linux run ip route and take the address after 'default via'. On macOS open System Settings, Network, then Details for the active interface and check the TCP/IP tab. On most networks using this subnet the answer will be 10.0.0.1.

Mid-range addresses like .138 are usually DHCP leases, and leases move. Ping the address, then check your ARP table (arp -a on Windows and macOS, ip neigh on Linux) to see whether a MAC address is still associated with it. If the entry is gone, the device has been renumbered, powered off, or moved to a different subnet, and no web interface will load.

10.0.0.138 is easy to mistype. 10.0.0.13 and 10.0.0.18 are separate hosts in the same subnet and may well answer, giving you a device you did not intend to reach. 10.0.138.1 and 10.138.0.1 are different subnets entirely inside 10.0.0.0/8. Type the address into the address bar rather than a search box, since four dotted numbers are often treated as a search query.

Try http://10.0.0.138 first. Many embedded interfaces on private addresses still serve plain HTTP, and forcing HTTPS produces a connection error rather than a login page. If HTTPS does respond, expect a certificate warning, since no public certificate authority issues certificates for RFC 1918 addresses. Cameras, printers and access points frequently listen on 8080, 8443 or 631 instead of 80.

Try the label on the device before guessing. Given the reported spread for this block, an empty username with an empty password is worth attempting, as is admin with a blank password, since together those account for a substantial share of reported cases. Many interfaces lock out for several minutes after repeated failures, so pause between attempts rather than cycling through lists quickly.

10.0.0.0/8 is subnetted in many ways, so an address you saw documented elsewhere may not exist locally. If your own address is 10.12.4.x with a 255.255.255.0 mask, 10.0.0.138 is off-subnet and reachable only if a router between the two segments permits it. Corporate and VPN networks routinely block that kind of cross-subnet management access by policy.

Usually not. It sits at host position 138 of the 10.0.0.0/24 range, and gateways are conventionally placed at 10.0.0.1 or 10.0.0.254. Nothing prevents an administrator from assigning .138 to a router, but by default it falls inside the range DHCP hands out to ordinary clients. On networks using this subnet, the administration interface is far more often at 10.0.0.1.

Nobody, and nowhere. 10.0.0.0/8 is private space reserved by RFC 1918 for anyone to use on internal networks, so the address is not allocated to a company, an ISP or a country. Any lookup tool reporting a city, provider or registrant for it is wrong. The only meaningful answer is whichever device holds the address on the specific network you are connected to.

There is no password belonging to the address itself, only to whatever device holds it. For devices reported on this block, admin / admin is the most common pair at around 38 percent, with about 35 percent reporting no credentials at all. Xfinity and Comcast SMC and Arris cable modems are documented with cusadmin / highspeed. Otherwise, read the sticker on the device or its manual.

Open your router's administration page, usually at 10.0.0.1 on this subnet, and look at the DHCP client or attached-devices list. It maps each leased address to a hostname and MAC address. Alternatively, ping 10.0.0.138 and then read arp -a on Windows or macOS, or ip neigh on Linux, to get the MAC address; its first three bytes identify the hardware manufacturer.

Private addresses are not routed across the internet. Traffic sent to 10.0.0.138 from another network is dropped by the first upstream router, and if it were delivered it would land on that network's own .138. To reach the device remotely you need a VPN into the network, or a port forward on the gateway pointing to it, which is worth setting up only for a device you control.

On that setup .138 is simply one of the addresses the modem has leased to a connected device. The default pool covers a large part of the 10.0.0.1 to 10.0.0.254 range, and .138 falls well inside it. Check the connected-devices list in the modem interface to identify it. The address is not fixed, so the same device may appear at a different number after a reboot.

A DHCP reservation on the router is safer than a manually configured static address, because it keeps the assignment in one place and prevents the same address being leased to something else. If you do configure it manually, use the correct mask for your segment, commonly 255.255.255.0, point the gateway at your actual router address, and pick a value outside the DHCP pool to avoid a conflict.
