Website Access Issue with AT&T Router and they DHCP assigned IP Address

I am encountering a persistent issue with accessing my website, "" (, through my AT&T router, which connects to a fiber internet connection. The router's public IP address is, and I also have multiple static public IP addresses on the same connection.

Problem Description:
The problem manifests when I attempt to access my website using any IP address assigned by the router via DHCP. In these instances, I am unable to reach the website. However, when I manually assign a static IP address to any of my computers, I can successfully access the website.

Additional Information:

  • I can successfully ping the machine and trace the route to it.
  • The issue persists even after AT&T's tech support has exhaustively gone through their troubleshooting steps, including the replacement of my router.

Request for Assistance:
I kindly request the assistance of experts to investigate this issue further as it continues to hinder my ability to access my website reliably.

The 70.251.x.x is your Dynamic Public IP?

The 108.167.141.x is a remote address that has nothing to do with your AT&T Fiber account?

When you say "when I manually assign a static IP address to any of my computers" do you mean you statically assign a private IP that gets NATted to the Dynamic Public or you assign one of the addresses from your Public Static block?

Have you tried doing a traceroute from each type of assigned address (i.e. once from the Dynamic IP and another from the Static)?

Can you share the output from those traceroutes?

Yes - 70.251.x.x is my Dynamic Public IP

Yes - 108.167.141.x has nothing to do with AT&T It is just where there webservice I am trying to reach resides.


In addition to the Dynamic Public IP that ATT assigns I purchase 8 public static IP address that I use to host locat servers.

The static IP's I am referring to are Public IP's

This is the Public Dynamic IP Address - I can not reach my webserver from any device connected this way

Hi @dsjames, this is not the type of experience we want you to have. We'd be glad to help!


We recommend that you set up an AT&T internet Static IP.


Furthermore, we would like to know if you are able to access your website using any other router or mobile device.

If so, we suggest you to log in to the Router configuration page and delete all the saved IP's and then, save the settings. Restart the router.


Hope this helps! Let us know how it goes.

Since the traceroute from both types of addresses reach your destination server and return (per the traceroute), It looks like AT&T is doing its duty in routing the traffic.  However, your webhosting company may be blocking traffic from your Public Dynamic IP or a larger block that includes your IP because of some past activity by a previous user of the IP (or someone in the same block).  The knee-(Edited per community guidelines) reaction of support from all webhosting companies when asked will usually be "No, we don't do that."  But you will remember that they tell you that they have enhanced security and IPS systems and other things that just would not work unless they do, indeed, do that to some traffic.

So, first, ask your webhosting company why the traceroute is working but your website doesn't get the traffic.  When they say ask the ISP, repeat that the traceroute shows that traffic is getting to the server and the server isn't answering.
