Does somebody know how to check what websites have been hosted on a given IP? Is there any tool that checks this?
I have found several websites that provide Reverse IP Lookup but as far as I know, this gets what domains are currently hosted on the IP. And I want to check historically what the IP has been used for.
Thanks!

I'm thinking to get Dedicated IP for my Shared Hosting (I'm running wordpress on shared hosting). Will it be beneficial for me? Above all, my shared hosting won't misbehave after i get it?
Certainly get it if you can afford it. No matter if it is shared or shared-reseller hosting (where you can assign your dedicated ip as your own shared ip for your websites).
It will make your websites more independent, especially if you use self hosted e-mail system on your shared hosting. Like Fahad said, there are IP blacklists, and when some bots hack weakly protected websites or flood their contact forms with spam the IP usually gets blacklisted soon after and all the websites which use that IP suffers from that.
You asked if it can break / misbehave something - yes it can, but its all solvable, if you know your stuff (changing DNS settings, etc) . You can always revert back to your shared IP, if you feel you are getting in too much trouble.
Yes as answered above, dedicated IP does help in a shared hosting environment where if the main shared IP gets blacklisted and the datacenter decides to null routes the IP address, all the sites sharing that IP will get offline.
In the past having a dedicated IP address was a requirement for installing SSL certificates, which had some SEO advantages as well. But, now you can install an SSL certificate without dedicated IP on any shared hosting. So I wouldn't say it's beneficial.
Do note that if you decide to get a dedicated IP for your site, having already a shared IP address, once IP is changed there is going to be some propagation period for the new IP. So you may get site loading issues for a few hours.
Dedicated IP is good for security due to the following reasons:
In case when the shared IP is blacklisted, all domains pointed to this IP will be involved. But if you are using the dedicated IP, you will not experience any issues as you have another IP.
It will be possible to reach the domain using the IP address. This option will allow you to avoid the DNS cache poisoning.
I am now just starting to understand Httpcontexts and server side logic. Total beginner.
I have understood how to read the http requests from a client and get the remote IP etc.
I came across the hostname property.
I believe hostname and domain are completely different.
My undersanding is that stackoverflow is the domain name.
Given its widespread reach, stackoverflow can have multiple servers and hence multiple ip addresses.
So is there a way to determine to which server a client is requesting to in asp.net core 2.0?
You are correct that stackoverflow.com is a domain name. A domain name points to an IP address. That's called DNS. stackoverflow.com points to one single IP address not multiple. There's probably a load balancer at that IP address which then points you to an available server, which is internal you can't see that, but that's another story.
If you ping stackoverflow.com you get:
The whole point of DNS is to not use IP address but a domain name.
I'm not sure why you would want to see the IP. Maybe this stackoverflow question can help: Resolve HostName to IP
First of all, I am helping my client to change his domain which should point to my company's hosting, but I don't know much about this type of situation.
The hosting is hosted on a server with multiple hostings. They all share the same ip address. And I need to point the domain to a particular hosting (which has a different domain pointed to it). What should I do?
Then, I use http://www.tcpiputils.com/ to look up the ip address for that particular hosting. And it displays "Found 30 domains hosted on IP address xxx.55.129.141.". Then what information do I need to point my desired domain to one of the hosting? A record, AAAA record, Nameservers????
We would like to use the Google Translate API from a host which doesn't have open access to the Internet. To setup the firewall rules I would need the list of possible IP addresses for www.googleapis.com. It is resolved to different IP addresses depending on the location. It seems to be difficult to create a future proof firewall rule.
Do you know how could I get the list of IP addresses or network ranges for the Google API servers?
The IP addresses used for any given googleapis.com server could change. Google doesn't have just one network block which they host all of their content out of, they have a bunch of them - and they change over time.
There are several ways you could setup your restricted network to allow access to *.googleapis.com without hard-coding IP addresses. I don't know anything about your setup, but I've found that using an internal proxy is often the best bet when you want to allow/restrict access to a domain.
Im building out an Azure hosted website, but it needs to reach into our home office to connect to some internally hosted web services. Our firewall is setup to only allow traffic over certain IP's, so we're looking to determine what IP range we need to allow access to.
Currently I'm still using the MSDN "Free" Azure subscription, so I don't know what options may be limited, but is there a way I can determine what source IP, subnet, whatever my Azure hosted site will attempt to call my web services from?
Thanks!
Be careful opening your firewall to the entire Azure datacenter IP ranges. Anybody can host anything in Azure, including malicious software, so if you open your firewall to the entire Azure IP range you may as well just open to 0.0.0.0-255.255.255.255 because in effect you are getting the same security.
A better option is to deploy your service and just whitelist that one IP address. That IP address is guaranteed to remain the same until you delete your service. With the ability to do in-place upgrades and VIP swaps there should be no reason why you would need to delete your hosted service and lose your IP address. If you ever do run into a scenario where you need to delete/redeploy you can always update your firewall at that time.
It sounds like this is what you're looking for:
