It depends on the DHCP server, it could be a few days or year or more.
1. dhclient -r This releases the current IP address lease 2. dhclient This requests a new IP address.
Then any computer that is turned on - while the DHCP server is down - can't get an IP address, and therefore can't communicate on the network. Also, a DHCP lease may expire - the computer got the IP address for 24 hours, for example, and the time elapses. Same problem.
That doesn't happen. If it does the workstation gives up the IP address and remains unconfigured until the DHCP server grants it another IP address.
169.254.10.1 is an IP address generated automatically by a computer when it is unable to lease an address from a DHCP server. It is called an Automatic Private IP Addressing (APIPA) address.

Renew lease is a configuration parameters for wireless network connectivity using an iPad. (And also using any device who works on a TCP/IP - DHCP "Wired" or "Wireless" network)On a DHCP (Dynamic Host Configuration Protocol) network, your device will receive a IP address as soon as you establish a communication to it. But your IP address will only being allocated to you for a certain period of time (This period of time is configured on the DHCP Server).Renew lease means that you will ask for another or longer lease of your IP address. Usally your iPad is supposed to keep the same IP address if it is still present on the target network after the lease period, because the DHCP protocol will do the procedure automatically for you.
depends on DHCP server configuration ))
Definitely check on the lease time; you don't want to make the lease time too long (or infinite) because that will waste IP addresses.
You can ping a static or dynamic IP address. The only difference is that a static IP has been issued to a subscriber semi-permanently. A dynamic IP has something called a 'lease time', and is only valid until the lease runs out. This lease time can be minutes, hours, days, etc. When the lease runs out, the machine that was using it needs to request a new IP address. Many times the last IP address will be leased out again, unless another machine made a request and got it first. To ping any IP address with Windows, Click the Start Menu. Click Run. Type 'cmd' in the box and press enter. When you see the black prompt screen, type 'ping xxx.xxx.xxx.xxx', where xxx.xxx.xxx.xxx is the IP address you want to ping. If you have a router, you can test connection to it by pinging 192.168.1.1 in most cases, unless you have changed the router's IP address. After the ping command is finished, it will report how long the packets took to get there, how many were lost, etc. If you have a 100 percent loss rate, the ping failed, most likely due to no connection.
An IP address of all zeros indicates a number of things:You released the network IP from the adaptor back to DHCPYou requested an IP address from DHCP but did not receive one (older Microsoft Operating systems reported an error this way, but current versions do not)Your IP address lease expired and DHCP did not allow a renewal.Essentially it means you cannot communicate on a network.
Yes. The client will renew the same address lease for as long as the DHCP server allows.
A temporary IP address assigned from an available pool is known as a DHCP (Dynamic Host Configuration Protocol) address. This type of address is dynamically allocated to devices on a network for a limited time, allowing them to connect and communicate without requiring a static IP configuration. Once the lease time expires, the address can be reclaimed and reassigned to other devices.
