We aim to make use of the measurements from the Giraffe Inner Bulge Survey(GIBS) and the Gaia$-$ESO survey (GES) to study the kinematics and distance ofthe carrier of DIB$\,\lambda$8620, as well as other properties. We successfullydetected and measured DIB$\,\lambda$8620 in 760 of 4117 GES spectra. Combinedwith the DIBs measured in GIBS spectra, we confirmed a tight relation betweenEW and $E(J-K_{\rm S})$ as well as $A_{\rm V}$, with similar fittingcoefficients to those found by previous works. With a more accurate sample andthe consideration of the solar motion, the rest-frame wavelength ofDIB$\,\lambda$8620 was redetermined as 8620.83 \r{A}, with a mean fit error of0.36 \r{A}. We studied the kinematics of the DIB carriers by tracing theirmedian radial velocities in each field in the local standard of rest ($V_{\rmLSR}$) and into the galactocentric frame ($V_{\rm GC}$), respectively, as afunction of the Galactic longitudes. Based on the median $V_{\rm LSR}$ and twoGalactic rotation models, we obtained valid kinematic distances of the DIBcarriers for nine GIBS and ten GES fields. We also found a linear relationbetween the DIB$\,\lambda$8620 measured in this work and the near-infrared DIBin APOGEE spectra at $1.5273\,\mu m$. We demonstrate that the DIB carriers canbe located much closer to the observer than the background stars based on thefollowing arguments: (i) qualitatively, the carriers occupy in the Galacticlongitude$-$velocity diagram typical rotation velocities of stars in the localGalactic disk, while the background stars in the GIBS survey are mainly locatedin the Galactic bulge; (ii) quantitatively, all the derived kinematic distancesof the DIB carriers are smaller than the median distances to background starsin each field.
