samba - Apr 2015 - smbclient 4.0.7 resolves host name to IP address for SMB2 but not NT1

We are having issues with smbclient 4.0.7 not working to clusters, because
it's resolving the host name ( 'default service =
dev3k1.my.domain.com' in smb.conf file ) to an IP address using SMB2, but
does not do it if is uses NT1( our desired behavior ).

Is there a way to turn off resolving the hostname in either the smb.conf file or
as a command line option to smbclient using SMB2/3 ?
