FAQs
Do the VCAM-I and VIP-Gateway use dynamic or static IP addresses?
While the VCAM-I and VIP-Gateway are assigned static IP addresses, they can operate on a DHCP network. In addition to its IP address, each device must also be assigned an alphanumeric name to make it easy for the user to remember and find. Every 16 seconds, the VCAM-I or VIP-Gateway broadcasts a UDP packet to a Domain Name (DNS) Server and identifies itself by name to the server. The server then compares the current device IP address to the one in the DNS database and automatically updates the IP address if it has changed.
DHCP, Dynamic Host Configuration Protocol, a protocol for assigning dynamic IP addresses to devices on a network. With dynamic addressing, a device can have a different IP address every time it connects to the network. DHCP also supports a mix of static and dynamic IP addresses.
DNS, Domain Name Server, an Internet service that translates domain names into IP addresses. Because domain names are alphanumeric, they're easier to remember. The Internet however, is really based on IP addresses. Every time you use a domain name, therefore, a DNS service must translate the name into the corresponding IP address. For example, the domain name NAPCOCAM01 might translate to 198.105.232.4.
UDP, User Datagram Protocol is connectionless protocol that offers a direct way to send and receive datagrams over an IP network. It's used primarily for broadcasting messages over a network.
