Reply from 191.168.0.29 bytes = 32 time = 1ms TTT 128
Reply from 191.168.0.29 bytes = 32 time = 2ms TTL 128
Reply from 191.168.0.29 bytes = 32 time = 1ms TTT 128
Reply from 191.168.0.29 bytes = 32 time = 3ms TTT 128

What do you mean by the last three parameters bytes = 32 time= 1ms TTL = 128?

bytes = 32:
time = 1ms:
TTL = 128:
