In Bind 9.8.1 Ubuntu server 12.04, I configured ENUM (Electronic Number Mapping).

1) Create named.conf.enum file in /etc/bind named.conf.enum content:

zone "" { type master; file "/etc/bind/"; };

2) Include the named.conf.enum in named.conf file

include "/etc/bind/named.conf.enum";

3) Make the file:

$TTL 86400 IN SOA (

2004011522 ; Serial

21600 ; Refresh

3600 ; Retry

604800 ; Expire

3600 ; Minimum TTL IN NS

; IN A IN NAPTR 10 100 "u" "E2U+sip" "!^.*$!!". NAPTR 10 101 "u" "E2U+h323" "!^.*$!!". NAPTR 10 102 "u" "E2U+msg" "!^.*$!!". NAPTR 100 10 "U" "SIP+E2U" "!^.*$!!".

I configured the ENUM in Bind 9 like above, Bind 9 was successfully restarted, when we test our configuration:

dig -t NAPTR

The server displays this message:

dig: couldn't get address for '':not found
