(abridged) We analysed data from observations of 17 INTEGRAL sources madewith the Swift satellite. We refine the position of the hard X-ray sources toan accuracy of a few arcsec. We then browsed the online catalogs (e.g., NED,SIMBAD, 2MASS, 2MASX, USNO) to search for counterparts at other wavelengths. Wealso made use of the X-ray spectral parameters to try to identify the nature ofthose sources. We provide the X-ray position with arcsec accuracy, identifypossible infrared and optical counterparts (when found), give the magnitudes inthose bands and in the optical and UV as seen with the Swift/UVOT telescopewhen observations are available. We confirm the previously suggestedassociations and source types for IGR J03532-6829, J05346-5759, J10101-5654,J13000+2529, J13020-6359, J15479-4529, J18214-1318, and J23206+6431. Weidentify  IGR J09025-6814 as an AGN for the first time, and we suggest that it may be aSeyfert 2. We suggest that IGR J05319-6601, J16287-5021, J17353-3539 andJ17476-2253 are X-ray binaries, with J05319-6601 being located in the LMC andthe other three possibly being HMXBs in our Galaxy. For IGR J15161-3827 andJ20286+2544, we find several possible X-ray counterparts in the IBIS errorregion, and we discuss which, if any, are the likely counterparts. Both arelikely AGNs, although the latter could be a blend of two AGNs. For IGRJ03184-0014 and J19267+1325, we find X-ray sources slightly outside the IBISerror circle. In the former, we do not favour an association of the Swift andINTEGRAL source, while it is very likely that IGR J19267+1325 and the Swiftsource are the same.
