hmm those i dont think they seem useless coz how can they just add the whole IP range to look at your server or website?

look at this:
124.115.4.193
1 124.115.0.28
1 124.115.0.25
1 124.115.0.19
1 124.115.0.16
1 123.125.66.93
1 123.125.66.85
1 123.125.66.75
1 123.125.66.74
1 123.125.66.70
1 123.125.66.64
1 123.125.66.60
1 123.125.66.59
1 123.125.66.58
1 123.125.66.121
1 123.125.66.117
