Why does my internal IP address keep changing?
Most of the time, the reason for a sudden change in an IP address is typically due to an interruption between your router and the internet. This could be due to power loss or from rebooting the system. Upon reconnection to the internet, your ISP will assign a new IP.
What causes an IP address conflict in DHCP?
A DHCP conflict is recorded when an MX Security Appliance detects two or more devices using the same IP address. This will likely cause connectivity issues for the devices sharing this IP address.
What causes wrong IP address?
The message “Invalid IP Address” indicates a problem with your computer’s network setup. Without a valid IP address your computer cannot use the network. A variety of reasons can make an IP address invalid, such as address conflicts with other computers and network configuration problems.
What are the two most common reasons for DHCP failure?
A DHCP error can be triggered by two things. The first reason can lie within the configuration on your computer or device that allows a DHCP server to assign it an IP. The second reason is the configuration of the DHCP server itself.
Is IPv4 same as IP address?
Internet Protocol version 4 (IPv4) defines an IP address as a 32-bit number. However, because of the growth of the Internet and the depletion of available IPv4 addresses, a new version of IP (IPv6), using 128 bits for the IP address, was standardized in 1998.

Why is the DHCP server not responding to my IP address?
If it originated from the local segment, the DHCP server compares the requested address to the IP address and subnet mask belonging to the local interface that received the request. If the address appears to be on the same subnet, the DHCP server will remain silent even if the address isn’t in the range of its pool of addresses.
Why does the DHCP server remain silent on some subnets?
If the address appears to be on the same subnet, the DHCP server will remain silent even if the address isn’t in the range of its pool of addresses. The DHCP server assumes that the address was assigned by another DHCP server on the same segment if it’s not from its own pool.
What happens when subnet mask/IP address fails to check?
The DHCP server assumes that the address was assigned by another DHCP server on the same segment if it’s not from its own pool. If the address fails the subnet mask/IP address check, the DHCP server checks to see if it came from a Superscope, if one is defined. If not, the server responds to the DHCPRequest with a NACK packet.
Is it possible to have two DHCP servers on the same server?
Normally, you should not have two DHCP responding for the same gateway (especially when servers are not on the same site, but this is also true when you have different scopes on a same server). You could try IPCONFIG /RENEW command to force the computer to empty its cache and try to get an address from the correct DHCP server
