Systems, methods, and computer-readable media for allocation and renewal of IP addresses

A dynamic host configuration protocol (“DHCP”) server comprising:

• at least one processor;
• and
• a non-transitory computer readable medium comprising instructions that cause the at least one processor to perform a method comprising:
• receiving, from a client device, a DHCP discovery message for allocation of an IP address;
• assigning an IP address to the client device for a first lease period based on the DHCP discovery message;
• providing the IP address that was assigned to the client device;
• receiving, from the client device, an IP address lease renewal request during the first lease period;
• determining a length of time the IP address that was assigned is in use by the client device;
• renewing the first lease period to establish a second lease period that is always longer than the first lease period based on the length of time the IP address that was assigned is in use by the client device;
• and
• providing the IP address for the second lease period.
