VoIP Cookbook: Test DNS for ENUM Query

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
