Today we have more constant connectivity to the internet. Most users do not disconnect their modems when not home or not in use. This change in use over the years has led to ISPs needing to keep a more consistent and live connection with a household modem. If the connection is still valid the ISP will move on and not disrupt service via provisioning a new IP address. There are multiple reasons they do not issue a new IP every time this lease renewal takes place:.
The beauty of our Household IP targeting system is that it adapts to the changing IP landscape via the ingestion of first party data it ingests over 1 million first party records a second. When an IP to a household changes, we have records indicating this to be the case, we then remove the pairing from our confidence interval until we have enough instances indicating this new IP represents the household.
Dana Bojcic. Some devices would continue to use the same ip until restarted or reset, other devices would not. Half way through the DHCP lease, the lease is renewed through the proceess. If the computer is always connected to the network it will keep the same IP.
If you are worried about a device losing it's address, then assign static. If the dhcp fails for any reason, any machine you are worried about will wind up losing it's ip after awhile, or after reboot. You can in a sense assign static ip's using dhcp reservations, but that still leaves the end system relying on a dhcp server that isn't responding for whatever reason.
As stated earlier it really depends on the device. If this is a Windows device I do believe you will run into a problem and the IP address will no longer be valid as it will switch over to a X address.
Some other device might hold the IP address information but I would not hold my breath. Section 4. Why not avoid the issue all together by swapping in a back-up device to do DHCP? As others stated before, there is no straight answer.
From this information, you can determine the lease time. In the example above, the lease expiry time is exactly 24 hours after the lease was first issued. This period may be shorter or longer for your connection, depending on your own network configuration. The DHCP lease time will be shown here as a base hexadecimal value.
For instance, the connection above has a hexadecimal DHCP lease value of 0x This converts to , the length of the lease in seconds, which is equivalent to 24 hours. You may need to check the manual for your router to determine if this is the correct way to connect, as well as determine the admin username and password to log in.
The DHCP lease value is named in various ways. For instance, on a TP-Link router, this value is called the address lease time. You can set this in minutes for this type of router, up to a maximum of the equivalent of 48 hours. Arianna Walker How often do dhcp clients refresh lease?
