does every Router provided by ISP has a unique IP address (public IP address) allocated to ISP by IANA?


Moreover, does each of these routers have NAT or PAT ability? if yes, who decides that one router has to perform PAT or NAT?

DHCP renewal of IP address with ISP denied

The router - in its capacity as a DHCP server - is providing internal IP addresses, for use on your LAN. The question around whether a static internal IP address is an alternative isn't really one for the ISP - they have no bearing or governance/authority on how you choose to assign devices IP addresses within your network. In my experience with ISPs here in the UK, they'll most likely tell you not to change it - or just not know what you are referring to.

The ISP provides a public-facing IP address, which is likely dynamic, but this has nothing to do with the internal IP addresses. That IP address is used by a device to identify itself to other devices on the network - including the router itself. The router then sends that devices requests out to the internet via the gateway.

Basically: save yourself the hassle of contacting your ISP and try and set the IP addresses for those devices manually. If you're unsure on which settings to use, do a quick "ipconfig /all" via CMD, make a note of the IPv4 address, Subnet Mask, Default Gateway and DNS Servers and then use those to manually input the settings as necessary.

 

IP ADDRESS

This problem usually sorts itself out automatically, but see the following for some suggestions:

If you keep getting these notifications, chances are that some device on your network is configured to use a static IP address that is within the range of addresses allocated by your router's DHCP server.

If you need some help in sorting out a situation like this, please provide the following information:

• the make and specific model of your router
• the make and specific model of every device connected to your network, including printers, TV set top boxes, Internet of Things (IoT) devices, etc.

If you have many devices connected to your network, download and run Advanced IP scanner (Advanced IP Scanner - Download Free Network Scanner.). This will list all of your currently-connected
network devices and show their IP addresses.

 

IP Address is blacklisted..Huh !


@treblefree, Ipconfig shows you the IP address assigned to you by your router, normally one starting 192.168.... These are private IP addresses for use on you internal network and are not used on the internet. Your router has an internal IP address (often 192.168.1.254) and also a public-facing IP address, assigned to it by your ISP. It is this address that is seen by the websites you visit and will be the one this site has blocked. The easiest way to find out yours is to Google 'what's my ip address'.

Who is your ISP? If it is BT then you will get a new public IP address if you reboot your BThub. The same applies to many ISPs, but not (apparently) Virgin, who assign you a fixed IP address.
