I have added an IP address in IIS7 in the IP address and domain restrictions. From what I have read this should block all traffic to the folder apart from the allowed IP address. For some reason this does not work. If I access the section from my work computer all ok, when I access it from my phone I can still see the page.
Does anyone have any idea why IIS is not blocking all the other IPs out?
Thanks
You have to put it to default block instead of default allow, and then put in an allow rule. Just having the allow rule is not enough. Click edit feature settings in the IP adress and domain restrictions, change the field "Access for unspecified clients" to Deny and you should be gold.

The website is reachable by host name but not by the ip adress specified in the A record. The DNS successfully resolves the request to the same ip specified in the A record.
Postman tells me: Error: Hostname/IP does not match certificate's altnames: IP: [...] is not in the cert's list.
Background: I have connected a Firebase application with a existing Domain. Firebase has generated a certificate for this website.
There are not enough IP addresses for all web sites to have a unique IP address. Firebase Hosting makes everyone's sites share the same IP address, and is able to distinguish requests for sites using the HTTP Host header from each request. This means the Host header is required. Postman will add that for you automatically if you use the domain name of your site, but it would have no idea what to use if you just provide an IP address.

I need to assign a public IP to my computer to access a CMS on a certain website.
e.g http://www.example.com/wp-admin, a wordpress website has blocked access to their CMS and they will only allow a certain IP address.
Now for temporary usage I go to https://www.whatismyip.com/ and it shows me my IP address, which I provide them and they give me access. But this IP is changing, so I often tell them this is my IP and they give me access using that IP and remove the other one. But I now want to get an IP that won't change?
So the Question is, Can I get a public IP that I can assign to my computer, and they it never changes ?
You can use a service as no-ip to "convert" your IP to a domain name like mycms.servegame.com, "servegame.com" it's a no-ip domain and the subdomain "mycms" it´s to identified your IP in the DNS.
No-ip service use a software that you can download in your PC, create an account, login and it´s all.
Or in some ISP modems you can configure your no-ip login information to redirect all your subdomain traffic to your IP.

I'm using a pfSense router and I'm desperately trying to configure a custom url (eg: myurl.ext) that should mapped by pfSense to a local server (eg: 192.168.0.x).
Like I do with my /etc/hosts and creating a line myurl.ext 192.168.0.x but on the pfSense level to do that for every device that should connect on the same network.
How could I achieve so? What is a name of what I am trying to do ? (DNS forwarding, Host override, dnsmasq, NAT....)
Found that by myself some time ago.
I used "DNS forwarder" service, and added custom host overriding and redirected to a specific machine with its IP.
(used address=/domain.ext/192.168.0.42 in advanced config in DNS forwarding service)

1)
Would it be possible to have a DNS A record point to a non-existent / supposed to be non-existent IP?
Essentially is there anything that prevents a DNS record from linking to anything?
Ex. Could someone go into a DNS record and change it to point to malicious things. ex. would it be possible for someone to point www.company.com --> 1.1.1.1 which is the IP for a malicious attacker?
2)
From this:
Ex. http://www.team-cymru.org/Services/Bogons/http.html
Those bogons. Would it be possible to have a DNS record point to one of them and some how 'fake' that they are this IP ?
I'm thinking yes via IP Spoofing?
Would there be someway for a website to emulate that it is actually a different IP address via a combination of DNS and IP trickery?
What prevents someone from saying that a certain DNS links to any IP. is there any sort of checking?
Could a DNS be used to hide the actual service provider and somehow provide service from IP (A) but 'say' it's providing service from IP (B). As DNS, I believe, is only supposed to tell you the IP to connect to I don't think this is possible yet I'm not sure.
Thanks,
Requesting for reopen: Why is this not a valid question? This from my standpoint is a valid cybersecurity question that I face.
IP addresses always exist. They are just numbers. What might happen is that a name is resolved to an address because there is a dns record doing so, whilst there is no server listeing at the address. Or even no system using that address.
If it's possible to 'use' such circumstances to whatever depends on a million things, so there is no way to give an answer without a clear question.

I have vsftpd set up at my home PC. I use a airtel broadband connection with a router, hence I have a public IP address and then a private IP address, none of which is static. Locally I can access my FTP through my private IP address, I wanted to know how would I access my computer though a remote location. I'm pretty sure
ftp://xx.xx.x.xx // my public IP wont work
You have to go into your router settings and give your PC a static local IP address. Then tell your router that every incoming request for ftp (usually port 21) is to be directed to that local IP address.
Specific instructions would be hard because every router is different and they all have a habit of changing their gui every chance they get.
Really surprised no one's answered this yet. Rocket science it's not.
