How do I read the results from Dunn's testtest? Specifically, what do the values in the table below tell me?

I have non-parametric data in 4 groups, and I first did a Kruskal-Wallis test to confirm that the groups' distributions were dissimilar from one another and the aggregate dataset. I then used Dunn's test to see which groups were dissimilar from one another, and which were not.

library(dunn.test)
dunn.test(data, g=area, kw=TRUE)
Kruskal-Wallis rank sum test

data: x and area
Kruskal-Wallis chi-squared = 1730.4401, df = 3, p-value = 0


                        Comparison of x by area                            
                            (No adjustment)
