Do I have to modify the reverse resolution file for wildcard domain name resolution?

Do I have to modify the reverse resolution file for wildcard domain name resolution? -- Linux Enterprise Application-Linux server application information. For details, refer to the following section. For example, the environment is as follows:

I set up lamp on linux. Then, we installed bbs and blog respectively. And implements
Www.yangjun.cn ---- Homepage
Bbs.yangjun.cn ---- Forum
Blog.yangjun.cn ---- blog

Everything is normal. What I need now is that any prefix (* .yangjun.cn) in the address bar can be parsed to the blog (blog.yangjun.cn.

I modified three files:

1./var/named/yangjun.cn (Forward parsing file)


CODE: [Copy to clipboard] @ 1D in soa yangjun.cn. root.yangjun.cn .(
42; serial
3 H; refresh
15 M; retry
1 W; expiry
1D); Minimum
In ns blog.yangjun.cn.
In a 192.168.1.85
Www in a 192.168.1.85
Bbs in cname www
Blog in cname www
Zhuzhan in cname www
Boke in cname www
Luntan in cname www
* In a 192.168.1.85
2./var/named/yangjun. rev (reverse parsing file)


CODE: [Copy to clipboard] $ TTL 86400
@ In soa yangjun.cn. root.yangjun.cn .(
2007051700; serial
28800; refresh
14400; retry
3600000; expire
86400); Minimum
In ns blog.yangjun.cn.

85 in ptr www.yangjun.cn.
85 in ptr blog.yangjun.cn.
85 in ptr bbs.yangjun.cn.
85 in ptr zhuzhan.yangjun.cn.
85 in ptr boke.yangjun.cn.
85 in ptr luntan.yangjun.cn.
3./usr/local/apache/conf/extra/httpd-vhosts


CODE: [Copy to clipboard]
ServerAdmin yangjun@qq.com
DocumentRoot/var/web/blog
ServerName blog.yangjun.cn
ServerAlias boke.yangjun.cn
ServerAlias * .yangjun.cn
ErrorLog logs/dummy-host.example.com-error_log
CustomLog logs/dummy-host.example.com-access_log common

As mentioned above, everything is OK.

But I am a little surprised, why is/var/named/yangjun. rev modified?
I cannot join

85 in ptr * .yangjun.cn.

This line does not work if you join this line.

> Nslookup 192.168.1.85

An error occurs.

[Root @ YangJun named] # nslookup 192.168.1.85
Server: 192.168.1.85
Address: 192.168.1.85 #53

** Server can't find 85.1.168.192.in-addr. arpa: SERVFAIL

Why is it that the file for reverse resolution does not need to be modified for wildcard domain name resolution?
