You have Data Saver turned on in the settings of Google Chrome. It proxies all your HTTP (not HTTPS or incognito) traffic through an optimisation server at Google to make the pages smaller.

I think I found my answer. So, the thing is, because I bought a shared hosting package, they also gave me a shared IP. My guess is, this IP has many websites next to mine and they're all accessible with this same shared IP address. The trick is the HTTP GET request's Host header! When I entered the shared IP directly in the address bar, the Host header ...

It should be noted that the following list has not been updated since November 2014. The following browsers do support SNI: Internet Explorer 7 or newer, on Windows Vista or newer. Mozilla Firefox 2.0 or later Opera 8.0 or newer (TLS 1.1 protocol needs to be enabled) Opera Mobile with at least version 10.1 bèta on Android Google Chrome (Vista or newer. XP ...

Note that the website that is reached through a domain name might not be hosted directly at the root of the IP address, i.e. example.org could map to 123.45.67.89/~example. This is common for normal web hosts since they can't allocate an IP address per website – that would be incredibly wasteful. For instance, if you do a DNS lookup of webmasters....

DNS has no concept of ports for older protocols such as HTTP, HTTPS, and SSL. DNS only points to the IP address. The port to connect to for a particular service is determined by convention. For example the default port for HTTP is 80, the default port for HTTPS is 443, and the default port for SSH is 22. The only way to override the default port is to ...

I have had server IP's blacklisted by Microsoft a few times and I have had them removed reasonably quickly. I noticed that after entering and joining anti spam related services that they recommend it was faster and easier. I recommend that you ensure that you can reply Yes to the below questions (except the last one) in the web form where you ask for ...

Yes - altering a HOSTS file locally to redirect a domain to an IP isn't the same as simply typing in that IP into the browser. The reason why is that in shared hosting, one IP address houses multiple domains. When you type in that IP address of "your" site (which is also the IP of other sites as well), the server can either a) Give an error b/c it doesn't ...

When you buy a SSL certificate, it is not tied to any particular IP address. It can be used on any server that hosts the content for that domain name. I personally have a load balancer on my website with multiple servers behind it. I have the same certificate installed on each of the web servers that are behind the load balancer. Each of those servers has ...

The original version of HTTP did not include any mechanism for the client to specify the host name as part of the request. It connected to the server and sent only the path portion of the URL. One of the early modifications to the HTTP protocol was to add the ability for the client to send other "header" information, including the host name. 20 years ...

The answers so far write about name servers and DNS as though they were two different things. They aren't. A DNS server is a name server. There are other name services, e.g. Corba's COSNaming, the RPC Portmapper, the Java RMI Registry, etc., but the DNS is what is usually meant. Also contrary to what is stated in other answers, the DNS contains the DNS ...

Hotmail, which is operated under Outlook.com now, is provided by Microsoft. You can request they remove your IP address by completing the form here (this may require signing up for Outlook.com first). It will take a few days for them to investigate the report, and if your IP address was not associated with sending Spam, you'll receive an email back from ...

BOTS, CRAWLERS and SCRAPERS use IP addresses in blocks, its rare to see one that will use the same IP address over and over. IP blocks are often sold, brought and then sold again! some of these blocks will resolve, some will not depending on the setup they use, because of this banning IP from a resolve is useless, because you risk banning real users, using ...

I think in order to clarify what is going on it helps to have an overview. The first thing to keep in mind is the internet runs on IP addresses, but people would rather remember words (domains) than numbers. This is a key problem that DNS is trying to solve. Another thing this lets you do is to change your server's IP transparently. This is great for ...

Especially if you have a shared hosting or a server of your own hosting multiple domains you can't access the "website" via IP. For your own server you could possibly define a primary domain that is reached if you enter the IP. For shared hosts that is impossible. As mentioned by @Ijacqu the IP could easily change. Another thing is duplicate content, so ...

I deal with this type of situation using my virtual host configuration. Under Apache, the first virtual host is the "default" virtual host. I configure it to serve a 404 error with the message 404 Not Found -- Hostname Not Recognized This server is not configured to serve documents for foo.example.com Then I create specific virtual hosts for each ...

From the official docs to verify Googlebot / Google: Note that Google does not recommend using a static "whitelist". You can verify if a web crawler accessing your server really is Googlebot (or another Google user-agent). This is useful if you're concerned that spammers or other troublemakers are accessing your site while claiming to be Googlebot....

Although both the IP address and domain might lead to the same content at any given moment, the content for each was likely indexed on different dates. Note the differences in the snippet for the IP address, which starts with "5 days ago", versus the snippet for the domain. It looks like much of the content there is dynamic and changes frequently, as other ...

Both answers are right to a point. I used to be a web host and a registered ISP. I was a presenter at the first ISPCon known as ISPOne for USRobotics and represented well over 1 billion dollars in sales in just the first quarter. I have been out of the industry for quite a while, but not too much has changed except for some of the offerings and some of the ...

Unless you have a dedicated IP address you cannot pull up your website using one. Shared hosts will put hundreds or thousands of sites on a single IP address. And as you can see the IP address itself will default to some page that is the default one for that server.

In simple terms: The nameserver tells the internet where the DNS records are located e.g. ns1.example.com and ns2.example.com Then the DNS at example.com tells the internet where to find different services. The A record is the IP address of the website. The MX record is the location(s) of mail servers and the order in which they should be selected. ...

This problem is related to spam actions against your GA account. Neither the WP plugin nor the php code would be able to record ghost visitor's (aka Ghost referral) IP address because they are hitting your GA account making HTTP requests by sending raw user interaction data directly to Google Analytics servers. In other words, they do not actually "visit" ...

You can host your website anywhere with good connectivity and get good rankings for a particular area - Google likely keys off the domain suffix more then the IP address (which hints at actual location). That said, page speed is taken into consideration so having stuff on the opposite side of the world might hurt -but that's not really the case here. ...

You'll need to create an A record to point the domain to the servers IP address. Log in to your domain registrar control panel or wherever your DNS records are controlled. Create a new A record. Set the domain.com. as the host and the value as the IP address. Allow up to 24 hours for the DNS record to propagate. For example:- Host: clubnetsem.com. Type: A ...

First things first. There are two domain names that we are talking about; Google.com and Googlebot.com. Doing a reverse look-up for Google.com would be misleading. Here is an answer I gave quite a while ago where I did an audit of the Google IP addresses used to crawl my site over 8 years. This is not the be-all end-all list, but could give an historical ...

IP ranges are specified in .htaccess using CIDR notation. The simplest rule that you could use would be Deny from 159.138.0.0/16 Which would block slightly too much: CIDR Range 159.138.0.0/16 Netmask 255.255.0.0 Wildcard Bits 0.0.255.255 First IP 159.138.0.0 Last IP 159.138.255.255 Total Host 65536 To block the exact ...

Just to clarify the question to prevent confusion: It's advised by Google to reduce the number of lookups for unique hostnames - see: Minimize DNS lookups As indicated there, hostnames are cached in the client's browser and OS. Using an IP address instead of a hostname for files hosted on the same host would therefore not be of benefit. For files hosted ...

Here is what happens when a user makes a request to your site: They do a DNS lookup for yourdomain.example.com which tells them it is a CNAME of SOMETEXTXXXX.dv.googlehosted.com They do a DNS lookup for SOMETEXTXXXX.dv.googlehosted.com and get the IP address 192.0.2.4 The browser opens a HTTP connection to 192.0.2.4 and sends the header: host: yourdomain....

PORT settings is a hosting server side setting and has nothing to do with the DNS. When pointing a domain or sub domain to an IP the hosting server will control the port element via a virtual host file. So in other words, simply put the A record to IP address and then have the virtual host file control what port the server operates on.

Are these bots that index my site(s) or are they malicious by nature and should be banned using an IP deny filter? You tell us. If they're interacting with your site as any normal user would there is no need to block them. If they're using the site more than visitors from other regions then your site may appeal to them then users from other regions. ...

Proxies run by national governments and ISPs will generally pass the carrier grade NAT (or in some cases, global) IPv4 address in the X-Forwarded-For header. Some proxies, such as those used by some UK ISPs to implement that country's censorship schemes, are transparent proxies, and the connection appears to come directly from the IP address of the end user,...
