Predicting Unknown Video Addresses

[searchinferu]

Excuse my lack of knowledge, but is possible to predict addresses of additional video files based on the address of say, twenty or thirty addresses from videos you already have? I would guess that few would be sequential, but perhaps the codes are not randomly generated either. So, if you had the internet address of X number of videos, perhaps there is a program that looks as the simularities of the addresses and predicts what the rest of a set of video addresses might be?
