BIND : Install / Configure2018/11/02 |
|
Install BIND to configure DNS server which resolves domain name or IP address.
|
|
| [1] | Install BIND. |
|
[root@dlp ~]# dnf -y install bind bind-utils
|
| [2] | Configure BIND. This example is done with grobal IP address [172.16.0.80/29], Private IP address [10.0.0.0/24], Domain name [srv.world]. However, Please use your own IPs and domain name when you set config on your server. ( Actually, [172.16.0.80/29] is for private IP address, though. ) |

# allow-query ⇒ query range you permit
# allow-transfer ⇒ the range you permit to transfer zone info
# recursion ⇒ allow or not to search recursively
# view "internal" { ** }; ⇒ write for internal definition
# view "external" { ** }; ⇒ write for external definition
# For How to write for reverse resolving, Write network address reversely like below
# Case of 10.0.0.0/24
# network address ⇒ 10.0.0.0
# range of network ⇒ 10.0.0.0 - 10.0.0.255
# how to write ⇒ 0.0.10.in-addr.arpa
# Case of 172.16.0.80/29
# network address ⇒ 172.16.0.80
# range of network ⇒ 172.16.0.80 - 172.16.0.87
# how to write ⇒ 80.0.16.172.in-addr.arpa
