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 ...

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 ...

Yes, you need a dedicated IP address for your SSL certificate. The following article explains exactly why: SSL certificates on Sites with Host Headers The key paragraph is: It's a chicken and egg problem: The host name is encrypted in the SSL blob that the client sends. Because the host name is part of the binding IIS needs the host name to ...

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 ...

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 ...

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 ...

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 ...

Providing initial explanation re difference between server-side stats and online stats for the benefit of other users: Apache access log analyses all the traffic to your server. StatCounter tracks all the visits to your site. Your server gets a lot more traffic than your site, because server traffic includes all the visits from robots, spambots, crawlers ...

For your website you would not need a dedicated IP unless you want to use SSL. But since most web hosters put your webiste on the same IP of your mails, a dedicated IP could make a huge benefit for your outgoing mails. With a shared IP you might be sharing the same server with spammers (or people sending out too many emails), some external internet ...

Looking at the wikipedia page on IP Addresses: The Internet Assigned Numbers Authority (IANA) manages the IP address space allocations globally and delegates five regional Internet registries (RIRs) to allocate IP address blocks to local Internet registries (Internet service providers) and other entities.

After reading Christofian's answer, I did some research and found out that the five Regional Internet Registry members (APNIC, AFRINIC, ARIN, RIPE, and LACNIC) each maintain a copy of the allocated IP address ranges and the associated countries on their public FTP servers. This information is updated daily and mirrored between the five servers. For example, ...

One IP could be for your web (HTTP/HTTPS) traffic, another could be for FTP or SSH access, another could be for mail, &c. If the publicly known IP (i.e. the one published to DNS) is separate to the one used for administration (only known by you and your team) then that would be a way of securing your server - by allowing different types of traffic over ...

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 ...

DNS has no concept of ports. 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 and the default port for SSH is 22. The only way to override the default port is to specify it in the URL (or on the command line for something like SSH). There is no ...

Downtime does not affect your rankings. Pagerank is based only on incoming links. However, excessive downtime may get your site temporarily removed from Google altogether until it comes back up again. Matt Cutts on Can a site's downtime affect its ranking?

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.
