Abstract: A method performed by a node (111) supporting operation on a Constrained Application Protocol (CoAP), but incapable of supporting operation on a Domain Name System (DNS) protocol. The node (111) encodes (402) a DNS query into a first message (601, 701), which has a format supported by the CoAP. The DNS query is mapped to the CoAP format of the first message (601, 701) based on a mapping scheme. The node (111) then initiates sending (403) the first message (601, 701) to another node (112) operating in the communications network (100). The another node (112) supports operation on the CoAP and on the DNS protocol. The node (111) finally receives (404) a second message (620, 706) from the another node (112), which has the format supported by the CoAP. The second message (620, 706) comprises the DNS response to the sent DNS query. The DNS response is mapped to the CoAP format of the second message (620, 706) based on the mapping scheme.
