I don't think this is very likely since this used to work, but it would be nice to be certain that they both use the same subnet mask. If your PC use 255.255.255.0 and the PS4 uses 255.0.0.0 (or vice versa), they won't be able to 'see' to each other. Last night I went to access my files on the ps4 and it suddenly says there is no. For the 10.x.x.x net, I've seen defaults for either of the two masks mentioned. I use Universal Media Server and have not had a lot of major issues. Fixed bug where the program would not start without an internet connection Checks for VSFilter (AviSynth subtitles plugin) in K-Lite Codec Pack Fixed crash when scanning some MP3 files with large. Home networks usually use either .x or 10.x.x.x, and .x is 'simpler' in that subnet mask 255.255.255.0 (/24) is pretty much always what's used. What is essential is that both devices use the same subnet mask, regardless of in which notation it is written.

For more information, see one of the many online IP calculators for example this one:

There isn't much consistency as to where what form is used, but 255.255.255.0 is the same as /24, and 255.0.0.0 is the same as /8.

To make it extra complicated, there are two ways to write subnet masks, either the dot-decimal notation or with a slash and the number of bits. With every IP address there is a subnet mask, for example 10.0.0.32 normally have either subnet mask 255.255.255.0 or 255.0.0.0.
