192.168.0.0/24 — the other default home subnet
192.168.0.0/24 is the second most common home subnet: 256 addresses, 192.168.0.0 to 192.168.0.255, with the router conventionally at 192.168.0.1. D-Link built its brand on it, and a long list of ISP-supplied CPEs hand it out by default.
Note the subtlety in the name: this /24 is only the first slice of the 192.168.0.0/16 private block. The /16 is the whole 65,536-address reservation; this page covers the specific 256-address LAN at the bottom of it.

Same shape as its famous sibling
Everything said about 192.168.1.0/24 applies here: router as gateway and DHCP server, pool typically starting at .100, static assignments kept low. The two subnets differ only in vendor preference — Netgear and Linksys leaned to .1.x, D-Link and many ISP boxes to .0.x. Functionally they are interchangeable.
The stacking trap
Where this subnet bites people is chaining: an ISP modem-router combo on 192.168.0.0/24 feeding your own router on the same range (or its .1.x twin) gives you overlapping routes or double NAT. The clean fixes are bridge mode on the ISP box, or renumbering one side — anything that puts both networks on distinct, non-overlapping ranges.

Frequently asked questions
What is 192.168.0.1?
The default gateway of this subnet and the admin address of D-Link routers plus many ISP-supplied modems. Browsing to it from the LAN opens the device's management page.
Is 192.168.0.0 a valid address for a device?
No — on a /24 it is the network address, which names the subnet itself and cannot be assigned to a host. Devices start at 192.168.0.1; the last assignable address is 192.168.0.254, with .255 reserved for broadcast.
What's the difference between 192.168.0.0/24 and 192.168.1.0/24?
Two separate 256-address subnets sitting side by side inside the 192.168.0.0/16 private block. Devices on one cannot reach the other without a router between them.
