Why it Happens? In order to open a website, the site URL entered on the browser address bar is to be resolved to an numerical IP address. This resolution happens through Domain Name System known popularly as DNS.
The technical reason for resolving host issue is that the DNS servers configured by your Internet Service Provider (ISP) takes long time to find a mapping IP address for the URL you have entered. This is probably due to change in ISP or change in DNS settings by your ISP.
Sometimes the DNS cache stored in your local computer or Chrome browser may also cause delay in finding the correct IP address of the site. Below diagram explains how the IP address is obtained from multilevel DNS hierarchy (part A) and then the actual content is retrieved from server using that IP (part B). Resolving host message is displayed on browser’s status bar during the process of part A. Resolving Host Process The easiest way to overcome resolving host problem is to directly opening the IP address in browser’s address bar which will skip the entire resolving host process. For instance enter 17.178.96.59 to open Apple website instead of typing www.apple.com. Since it is practically not possible to remember IP addresses of all the sites and one site may have multiple IP addresses or one IP is assigned to multiple site in shared hosting scenario, it is necessary to solve the issue.
Here is the list of possible solutions explained in step by step for fixing the resolving host issue. (Network setting changes are explained for Windows users, the same can be followed in Mac with appropriate changes). How to Fix Resolving Host Issue? Depending on the root cause of the issue one of the below solutions should fix the resolving host issue:. Change your DNS servers to public DNS servers. Clear DNS cache of Chrome browser. Clear DNS cache of your local PC or Mac.
Disable DNS prefetching or prediction on Chrome. Change LAN settings. Modifying hosts file. Don’t use unreliable proxy and VPN. IP conflict due to multiple computers connected to the same wireless router.
Contacting your Internet Service Provider (ISP). Each option is discussed detail in the following sections. Option 1 – Change to Public DNS Changing the DNS servers in your network settings is the straight forward way of fixing this issue. You can use any of the public DNS servers available in the net. Since all your internet activities will be routed through the DNS servers for resolving domains, only use known and reliable server address and avoid using unknown free server details for security reasons. Here we used the IP addresses of for Preferred DNS server as 8.8.8.8 and Alternate DNS server as 8.8.4.4 for TCP/IPv4 as shown in the picture below. If you use Windows, open the “Command Prompt” and enter the command “ipconfig /flushdns” and you will see a success message.
Press “Windows key + R” and enter “cmd” to open command prompt in Windows XP/Vista/7. Use power user options by pressing “Windows key + X” to access command prompt in Windows 8/10. If you use Mac, open “Terminal” application from “Utilities”, enter the command “dscacheutil -flushcache” and you will not see any success message. If you use OS X version 10.5.1 and below then use the command “lookupd -flushcache” for clearing the DNS cache. Option 4 – Disabling DNS Prediction or Prefetching If the issue is not resolved after changing to public DNS servers or clearing the cache as explained above then try the following option. Open the Chrome browser window and click on the “Customize and control Google Chrome” icon shown in the upper right corner (it should be like three dots in vertical). Select “Settings” option as shown in the picture below.
Disable DNS Prefetching in Google Chrome Basically Chrome try to resolve all IP addresses of the links on a webpage. Though this is intended to improve the loading speed while you read the content on that page, this may negatively impact depending on the number and types of links. Note this option may be different on different versions of Chrome like “Predict network actions to improve page load performance” or similar to that. Option 5 – Changing LAN Settings If you see a “Resolving proxy” message in the status bar it might be due to your LAN settings. As explained in the option 4, open Chrome’s settings and click on the “Show advanced settings” link.
Navigate to “Network” section and click on “Change proxy settings” button. Go to “Connections” tab and click on “LAN settings” button as shown in the picture below. Remove Automatic Configuration Settings Option 6 – Modifying Hosts File Hosts file is located in local PC or Mac and controls the resolution of a domain name to an IP address before any other DNS resolution takes place.
Adding IP and the corresponding domain name entries in hosts file helps to overcome resolving host issue since the IP will be directly obtained from the hosts file without looking further. This will be useful to faster few frequently visited sites but it is really hard to maintain the IP address of each site you visit in the hosts file. Below picture shows the hosts file entries in Window 8. Check out the article on. Adding Entries in Hosts File in Mac Option 7 – Disable Proxy and VPN Using proxy server or helps to hide your identity and browse the web anonymously.
It also helps to access blocked websites by government, organizations and schools. Unfortunately many of the people use these services to do illegal activities. There are scam monitoring services on the web that updates the IP addresses from where the scams are originating. Companies like Google and other web developers use these scam monitoring services database to filter unwanted network. Most likely all those free services will get blocked since proxy and VPN companies share the same server details with large number of users. You will also see due to reasons like this. So ensure not to use free proxy and VPN services and try to get premium services like or to avoid seeing resolving host message.
Option 8 – IP Conflict The last option is to restart your computer or restart the internet connection by disconnecting the modem power and connecting it again. Nowadays it is a common scenario in a house having laptop, iPhone or iPad and all are connected to the same router. You may notice a Windows system error showing an IP conflict message in your taskbar’s tray as shown in the below picture. IP Conflict Error in Mac Though it may not cause resolving host issue it will interrupt your internet connection and delay the loading of sites. Restarting your modem or computer will resolve this IP conflict issue.
Option 9 – Contact Your ISP Contacting your ISP, if none of the above mentioned solutions at browser, computer and router level work for you. Discuss the issue with your Internet Service Provider (ISP) along with the URLs of the sites you are trying to access.
Your ISP can check at their end and confirm whether they are blocking those sites. They can also provide alternate DNS servers or change configuration settings at their side to overcome resolving host issue. I tried option 2, waiting to see if it will work. I purchased my new computer from Costco and they said the problem is with my router, and to buy one. My internet provider said it’s not necessary because the modem that I rent has one built in. When I called tech support for my computer, they said it could be the wifi signal, and I should return the computer for another one. I’m confused, does the “resolving host” issue have to do with the info you provided on this page, or is it my computer?
I use Google Chrome, but when I get the “resolving host” message, I can’t seem to get anywhere using Mozilla either? Narrow down your issue with the following actions: 1. Open a local website (or IP address of any website) to ensure you are connected to internet. If not the problem could be on your PC or router not configured correctly. Try to connect your PC with some other networks (other than your ISP) – this will help you identifying the issue is on the PC or on the network at ISP side. Try connecting directly with LAN network cable to see if it is a router issue. PC, browser, router and ISP – all using DNS settings to provide fast results.
So the problem could be on anywhere. For Comcast – Disabling IPv6 in my PC’s network connection properties worked, although I wanted to dig a little deeper. I can’t disable IPv6 altogether in my router, as it seems Comcast needs it to connect (at least on my residential line – my business line doesn’t seem to care).
The problem for Comcast seems to lie in their DHCPv6 server (at least when I was having my problem). When I let my router “Get IPv6 DNS Server Automatically” the resolving host problem occurred. When I manually selected my IPv6 DNS Servers from the router (I used Google’s IPv6 dns servers), it fixes the problem. Interestingly, when I manually select IPv6 DNS servers on my PC, it doesn’t work.
I don’t know enough about networking to know why.
