172.30.30.30 router login
To open the admin panel, type 172.30.30.30 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.
172.30.30.30 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 credentials are on record for this address, and because .30 is an unusual place for a gateway, the device answering may not present a router-style login at all. It could expose a management web interface, an SSH service, an application port or nothing user-facing. Identify the hardware or software first, then consult its own label, manual or vendor documentation for the shipped defaults. In a lab or corporate subnet, the account is often one an administrator created rather than a factory default.
How to log in to your router
Type 172.30.30.30 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 172.30.30.30, 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
Before resetting anything, confirm what you are resetting. If 172.30.30.30 is a statically configured host, a factory reset returns it to DHCP and it will very likely reappear on a different address, so plan how you will find it again. Reset also discards local configuration such as certificates, application settings and stored data on some appliances. Where the device is virtual, a snapshot rollback is usually safer and faster than a hardware-style reset. Resetting the network's router instead will not help and will disrupt every other host on the subnet.
172.30.30.30 falls in 172.16.0.0/12, the middle RFC 1918 range. That block uses a 255.240.0.0 netmask, holds 1,048,576 addresses and spans 172.16.x.x through 172.31.x.x only. The boundaries matter: 172.15.x.x and 172.32.x.x are ordinary public space, so a 172 address is not automatically private. With a second octet of 30, this one is comfortably inside the private portion.
Its /24 is 172.30.30.0/24, usable from 172.30.30.1 to 172.30.30.254, broadcast 172.30.30.255. The repeated 30 pattern is memorable rather than meaningful, and .30 is not a position routers usually occupy. It looks far more like a fixed assignment to a host: a hypervisor, a lab appliance, a printer, a camera or a statically configured server. Four further addresses in the same /24 are already documented, suggesting a populated working subnet.
This range shows up in mid-size business networks, test labs, VPN subnets and container bridge networks. Anyone arriving here has usually seen 172.30.30.30 in a scan, a log line or a connection string and wants to know what kind of thing it is.

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.
