Basically: the browser includes the domain name in the HTTP request, so the webserver knows which domain was requested and can respond accordingly. HTTP requests Here's how your typical HTTP request happens: The user provides a URL, in the form http://host:port/path. The browser extracts the host (domain) part of the URL and translates it into an IP ...

I have this explanation for non-tech people. Jack, Jill and Joe live at a dormitory, and they don't have cellphones. In the phonebook, they are all listed with the same number. (A-record) You dial the number, and somebody picks up the phone; you say "I'd like to speak to Jill", and you get her on the line. Instead of an A-record (A phonenumber/IP-adress)...

As from what I understand the DNS link the domain name with the IP address of the server the website is stored on, does that mean each server can only hold one website? First, you need to understand that there are a number of distinct concepts here. Web site, a group of web pages that form a coherent whole. IP address, a numerical address (32-bit for ...

The answer is a bit more complicated than some of the answers have made it out to be. When you perform a DNS lookup you MUST get an IP address (A record for IPv4, AAAA for IPv6). You have to be able to open a socket over TCP/IP to communicate or the whole thing fails. That address may represent a server or it might represent a load balancer. It could even ...

Why do I have an IPv4 and IPv6 address at the same time? Because your ISP supports IPv4 and IPv6. They're not mutually exclusive. (And somewhat unfortunately, they are entirely separate – an IPv6 address cannot be used for speaking IPv4, and an IPv4 address cannot be used with IPv6. [It's like Skype and Viber, if you want to use both, you'll have separate ...

Yes. NAT or call it PAT is usually configured by default as this is what your router is made for. But if you want to make services/ports accessible from the Internet, you need to activate and configure port forwarding (port to port). For example if you have a web server running on one of your desktops/laptops and you want to make it available on the Internet,...

172.68.34.125 is a CloudFlare IP address. CloudFlare is a service that website owners use for DNS, CDN and security purposes, which performs routing and redirection to sites. As such it is quite likely that when cloudflare is in play, the IP pathway to reach the site varies based on their routing decisions. Generally, to configure your site to use ...

Just based on the information you provided, which is none, the answer is no. More than likely, another device on the network is forwarding a public IP to the internal private IP of the device. Depending on your access to the device, you could look at the IP configuration of the network, as it might have the public IP listed. It could be possible the ...

Short answer is no. The best you can do is make educated guesses - how educated depends on how desperate you are and what resources you have at your disposal. Sources to inform the guess would include (but are probably not limited to) Hints from the IP address - at least in NZ, historically addresses were broken down into size ranges (smallest being a ...

You are totally correct. If you see something like AAAA:BBBB:CCCC:DDD::EEE, multiple numbers and letters separated by colons, it is an IPv6 address. On the contrary, IPv4 looks like 12.34.56.78, only containing numbers and separated by dots. Currently, there are only those two types of IP addresses. Other address formats exist, however of course, for ...

First we should make some terms clear: Your local IP addresses are private addresses which cannot be used on the Internet because they are not unique there and cannot be unambiguously routed in the scope of the whole Internet. Your static IP address 202.63.90.24 is your public IP address (unique in the Internet) which was statically assigned to you ...

Yoy can try to modify the IpHostNumber (Contains the IP address of the host in dotted decimal notation, omitting the leading zeros.) attribute in Properties of Host - Tab Attribute Editor. Search for this attribute and edit with the IP that you need. Regards P.D Sorry for my english ;)

Looks like bouncers could be considered layer 7 proxies. They manage an application layer connection downstream and provide an application connectivity endpoint upstream. So the proxy itself can stay connected even when the user is not. This could provide a number of services such as logging, notification, and presence even in the face of poor or irregular ...

Why not? IPv6 works. IPv4 works. With IPv6, you can communicate with other computers that are using IPv6, without needing to use some sort of device performing complicated IPv4-to-IPv6 translation in the middle of the communication. With IPv4, you can communicate with other computers that are using IPv4, without needing to use some sort of device ...
