no access-list ping_acl permit icmp any any

no access-group ping_acl in interface inside

You do not need this acl to allow ping from the inside interface. Removing this acl will solve your dns problems etc. If you want to ping to the outside you only need to allow the reply in the outside interface acl like so...

access-list acl_out permit icmp any any echo-reply
