Configure DNS server which resolves domain name or IP address in CentOS
Configure DNS server which resolves domain name or IP address.
|
[root@dlp ~]# yum -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 [server.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. # 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
# 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
