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 ...

If a packet is not acknowledged within the expected timeout, an asterisk is displayed. From http://en.wikipedia.org/wiki/Traceroute However zyzzyva.site5.com did eventually respond which is why you have line 16.

Yes, it's normal. ISPs, particularly AOL and mobile providers, can route traffic through different proxies which will change the IP address of a user as they surf the web. Users using a proxy server can also experience this. This is why depending on a static IP address from a user during a session is not recommended for any kind of identification system on a ...

There are other answers here that address SNI which allows multiple SSL certificates per IP address. Yes, you need a dedicated IP address for your SSL certificate.

Just like with visitors, search engine bots go wherever the domain and links in your site point to, and index links according to which belong to your site, independent of the IP address it's hosted on. So changing IP addresses is just like doing a 301 redirect (without the redirect) - it won't affect your search engine results or position. Two potential ...

In the context of web hosting, a shared IP is an IP address shared by multiple websites usually on the same shared server but could also be across different servers, whereas a dedicated IP gives your website a distinct IP from others. If you don't know whether you need a dedicated IP or not, then you most-likely don't need one. The primary reason one uses a ...

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 ...

As long as the domain and content remains the same, changing IP addresses should have not affect on SEO. Moving from Canadian to US IP's wont affect your SEO.

For years, I haven't seen a site ranking in Google that doesn't have a domain name. That doesn't mean it isn't possible, but few (if any) sites are doing that now. Here are a bunch of reasons that you should get a domain name: IP addresses cannot be moved from one web host to another the way that domain names can. IP Addresses change. It is very ...

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 ...

Another reason is that typically 3 packets are sent to each machine, and some machines will only respond to the first packet no matter what. If the problem is just a timeout issue, you can set the -w parameter to the number of seconds you want to wait; e.g., traceroute -w 10 google.com will wait 10 seconds instead of the default of 5 seconds.

Traceroute sends packets to the destination with the field "time to live" (TTL) equal to the number of hops. Every router decreases the value of TTL of an incoming packet and if it sees an incoming packet with TTL = 0 then drops it, otherwise it decreases the value and sends it further. At the same time it sends diagnosing information to the source about ...

As paulmorriss mentioned in the comments, most major web servers do this automatically anyways, with their server logs. These logs contain UA strings, IP addresses, and much more. I don't know of any law on the books that would explicitly forbid this, but I would say that you should probably include in the Terms of Service the fact that you collect this ...

In 000-default (usually in /etc/apache2/sites-enabled/000-default) You can use the VirtualHost tag to separate different sites. <VirtualHost *:80> DocumentRoot /var/www/example1 ServerName www1.example.com </VirtualHost> <VirtualHost *:80> DocumentRoot /var/www/example2 ServerName www2.example.com </VirtualHost>

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 ...

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 ...

A whois record should display your registration info unless you chose to use private registration. And a whois search on an IP will show who the ip block is registered to, and is almost always your ISP. If you want to have your own company info show up in an IP lookup, then you need to obtain a provider-independent address space. This can be done through a ...

I want to change language dynamically by using PHP code,this done based on the requesting IP address. Please avoid automatic language detection based upon origin IP or, if you insist upon using this technique, make it easy for users to select a different language - you will inevitably find that some of your users' IP addresses do not accurately ...
