I have gone through so many sites and did tried all the possible solutions like :

 With ASP.NET 4.0, add the following lines to your web.config: 

<system.serviceModel> 
     <serviceHostingEnvironment multipleSiteBindingsEnabled="true" /> 
</system.serviceModel> 




With ASP.NET 2.0/3.0/3.5, add the following lines to your web.config:


<system.serviceModel> 
     <serviceHostingEnvironment> 
          <baseAddressPrefixFilters> 
               <add prefix="httplinktoyoursite"/> 
          </baseAddressPrefixFilters> 
     </serviceHostingEnvironment> 
</system.serviceModel> 

 

They may working in different scenarios but in my case i have to remove the one of the bindings in IIS.

 

 

Remove the binding with IPAddress.
