There are many types of DNS records. It may be difficult for beginners to determine which DNS record is required or how it is set up. In this article, you will learn how to check the PTR record and whether it is set for an IP address.

What is PTR recording?

In short, the PTR record is like an inverted version of the A record. A record maps the domain name to an IP address. PTR maps the IP address to a hostname. However, these two records are independent. For example, a record of hostinger.com may point to the IP address 21.21.128.xx, while 23.23.128.xx can be mapped to a completely different hostname.

Good afternoon on this article I will discuss setting point to multipoint before my friends already know the difference between point to point with the point to multipoint, let me repeat again point to point means one point to point opponent while pointing to multipoint ie one point to many points that can be connected.

I will share a tutorial on how to connect the Router a million people that is Mikrotik with the access point from Cisco Vendor named Aironet

okay we will just explain a little bit about Access Point ( AP ) Aironet from Cisco

Introduction with Cisco Access-Point Aironet
In Cisco Aironet there are 2 modes for operational:

1. Lightweight Access Point ( LAP ), in LAP for operational use Controller for centralized AP management, called WLC
2. Autonomous Access Point ( AAP) or sometimes called “Standalone” ^ _ ^, in the AAP, is not required Controller, so each AP has their own management

Generally speaking, mod_rewrite converts clean and user-friendly URLs to websites. As you can tell by its name, it rewrites the URL. A great way to clear your website’s URLs.

How Apache mod_rewrite Works

When a user enters a URL, the URL is checked against a list of predefined rules. The rules are to search for specific phrases or keywords. If the URL contains the keyword and conforms to the rule, it will be replaced by a predetermined set of URLs.
