As we enter url in browser. browser check IP address in host file for domain name. And If IP address is not find in there than how browser find IP address from internet for particular domain name?
DNS is what you're looking for.

I use an application the makes calls to apps reunning on other servers. I would like to get the IP address of one of those servers and the source page doesn't reference either the called URL or IP address.
My idea is to ping the currect page to get the server IP address.
I have built a FreeIPA nameserver that is accessible from within my internal network, however I am unable to get this working for external traffic.
My domain name server setting has been updated with my domain registrar to use my name server. The domain algobuilder.co.uk is set to use nameserver ns1.algobuilder.co.uk and my public static ip address (31.125.181.141). A simple ping from outside my network confirms that algobuilder.co.uk is resolving to my public static IP address.
It appears that external traffic is not using the nameserver ns1.algobuilder.co.uk to resolve to my nameserver. I have opened port 53 on my router and forwarded it to the internal ip address of my nameserver.
I need CertBot to be able to access my nameserver txt records, but it doesn't seem to be able to find them.
Any clues to what I am doing wrong. Thank you.
When I'm accessing any host via IP address, it is showing SSL error.
Example.com => 192.168.1.1 (IP address)
Suppose if I want to access https://example.com, it works fine.
If on the other hand, accessing the hosts by its IP address like https://192.168.1.1, it shows SSL Error.
Is there any configuration missing here. Do I need to add the IP address in SAN configuration?
If you want to access a web site by IP address you need to first configure your web server to actually provide this web site on this IP address and then you have to include the IP address as SAN into the certificate served at this IP address. Note that there are different types of SAN: DNSName and IPAddress. The correct type would be IPAddress but some clients actually wrongly expect type DNSName - so you better add the IP address with both SAN types.
I'm trying to find the authoritative name servers for a given IP address and as far as I can see the only way to find the name servers is by using the domain name of the IP.
How do I convert the IP to domain name (not hostname)?
Or how do I find the authoritative name servers for any IP address?
You can use dig to get PTR RR, for example:
dig -x 8.8.8.8
I have Static IP, i would like to access website using static IP as well using domain name.
I have below DNS entries to for my domain, i am not sure what setup i need to do to make it works.
when user access my site using domain name they should be able to access. Also when someone want to access using IP address they should be able to do that.
www 14400 IN CNAME example.com
example.com 14400 IN A 50.63.147.111
If anybody have idea please let me know.
Thank you

If you can't access your IP address, then it isn't because of your DNS. DNS stands for domain name system and translates domain names TO IP addresses. Thus, you must already have a reachable IP address for your A record to be meaningful. Make sure that you've configured your server correctly (Apache?) and that the necessary ports are open in your firewall (iptables).
Check that your domain registrar is pointing its name servers to the authoritative name server (the server with your zone file) for your domain.
