One of the IP addresses for Yahoo is 216.109.118.69. For example, imaging that we wanted to make it so that if you typed in instead of going to Google we would go to In order to do this you would need to find out one of the IP addresses of Yahoo and map to that IP address. The HOSTS file is a text file that contains IP addresses separated by at least once space and then a domain name, with each entry on its own line. This file allows you to create mappings between domain names and IP addresses. Almost every operating system that communicates via TCP/IP, the standard of communication on the Internet, has a file called the HOSTS file. There is another way to resolve domain names without using the Domain Name System, and that is by using your HOSTS file. If you would like a more detailed explanation of the Domain Name System you can find it here: The Domain Name System The device will then open a connection directly to the IP address and perform the desired operation. The DNS server will then query other servers on the Internet that know the correct information for that domain name, and then return to the device the IP address. This is done by the device querying its configured DNS Servers and asking that server what the IP address is for that particular domain name. In order to get that IP address, DNS is used to resolve that domain name to its mapped IP address. Whenever a device connects to another device on the Internet it needs to connect to it via the IP address of the remote device.
#HOSTED APPLE SERVER WINDOWS#
On almost all operating systems whether they be Apple, Linux, Unix, Netware, or Windows the majority of resolutions from domain names to IP addresses are done through a procedure called DNS.ĭNS stands for Domain Name System and is the standard domain name resolution service used on the Internet. The way these hostnames are resolved to their mapped IP address is called Domain Name Resolution. Therefore when you type a domain name in your program that you wish to connect to, your application must first convert it to an IP address that it will use to connect to. Just wanted to share.When using the Internet most people connect to web sites, ftp servers or other Internet servers by connecting to a domain name, as in Internet applications, though, do not communicate via domain names, but rather using IP addresses, such as 192.168.1.1. I don't really notice any performance lag on the actual VMs, just a little concerned about the messages on vCenter server about the device latency. We have the SAN connected with 10G cables to the Xserve hosts on Intel X520-DA2 adapters. I'm starting to think it's the type of disks we used in the SAN. On the SAN we built, it's running FreeNAS, every once in awhile I'm seeing messages about device performance has deteriorated and I/O latency increased. The only issue I'm having right now is with the storage.
We picked up 2 refurbished Xserve's on eBay from a good company, we already had one Xserve in house. I would recommend using the Xserve (early 2009) model if you are going to do this. Things are working well so far, I'm fairly new to VMware and learning new things daily. We are using iSCSI SAN for storage on a "home grown" NAS. Right now I have a 4 VM servers running and am working this summer to migrate 6 physical servers to the VM environment. We are running VMware ESXi 5.0 on all 3 hosts. I have 3 Xserve's, dual CPU, 8-core models. I am doing OSX server virtualization utilizing Xserve (Early 2009).
