这是我的区域文件:

$TTL 1H
@       IN      SOA     ns.e164.arpa.   hostmaster.e164.arpa. (
                        199802151       ; serial, todays date + todays serial #
                        8H              ; refresh, seconds
                        2H              ; retry, seconds
                        4W              ; expire, seconds
                        1D )            ; minimum, seconds
;
                NS      ns              ; Inet Address of name server
;
;
2.8.0.2.0.8.0.0.8.5.6.1.9.4.e164.arpa. NAPTR 0 0 "u" "E2U+sip" "!^.*$!sip:+49165800802082@ibcf.core.test;user=phone!" .

2.8.0.2.0.8.0.0.8.5.6.1.9.4.e164.arpa. NAPTR 0 0 "u" "E2U+sip" "!^.*$!sip:+49165800802082@ibcf.core.test!" .

3.2.1.0.5.5.5.5.1.2.1.e164.arpa.       NAPTR 0 0 "u" "E2U+pstn:tel" "!^.*$!tel:+1-215-555-0123;npdi;rn=+1-215-555-0199!" .

3.2.1.0.5.5.5.5.1.2.1.e164.arpa.       NAPTR 10 100 "u" "E2U+pstn:sip" "!^.*$!sip:+1-215-555-0123;npdi;rn=+1-215-555-0199@ibcf.core.test;user=phone!".
;
;
; A records:
;
ns              A       10.10.240.4
localhost       A       127.0.0.1
ns              AAAA    3001:10:240::4

然后我跑:

dig naptr 3.2.1.0.5.5.5.5.1.2.1.e164.arpa @127.0.0.1

它运作正常,结果是:

; <<>> DiG 9.9.4-P2 <<>> naptr 3.2.1.0.5.5.5.5.1.2.1.e164.arpa @127.0.0.1

我的问题:

我有很多地址像(3.2.1.0.5.5.5.5.1.2.1.e164.arpa.)来查找,但我不想写这个区域文件中的每条记录。

dns是否支持区域配置文件的正则表达式? 就像:

3.*.e164.arpa.       NAPTR 10 100 "u" "E2U+pstn:sip" "!^.*$!sip:+1-215-555-0123;npdi;rn=+1-215-555-0199@ibcf.core.test;user=phone!".

第一个字符3将符合此规则。
