We can use the dig command on the localhost of the DNS server to query the ENUM entries, for example,
$ dig NAPTR 0.0.0.2.5.2.6.e164.id @127.0.0.1
The output would be approximately
; <<>> DiG 9.6.1-P1 <<>> NAPTR 0.0.0.2.5.2.6.e164.id @127.0.0.1 ;; global options: +cmd ;; Got answer: ;; ->>HEADER<<- opcode: QUERY, status: NOERROR, id: 10744 ;; flags: qr aa rd ra; QUERY: 1, ANSWER: 1, AUTHORITY: 1, ADDITIONAL: 1 ;; QUESTION SECTION: ;0.0.0.2.5.2.6.e164.id.
