3. IP Address Configuration Your Axis network camera supports both IP version 4 and IP version 6 Both versions may be enabled simultaneously and at least one version must always be enabled When using IPv4 the IP address can be set automatically via DHCP or a static IP address can be set manually If IPv6 is enabled your camera will receive an IP address according to the configuration in the network router There are also options for setting up notification of changes in the IP address and for using the AXIS Internet Dynamic DNS Service For more information on setting the IP address please see the online help Notes e DHCP is a protocol for automatic IP address assignment on a network IP address assignment via DHCP may lead to the situation where the IP address changes and you lose contact with the camera Configure the options for notification of IP address change under Services to receive notification from the camera when the IP address changes e Alternatively if your DHCP server can update a DNS server you can access the AXIS 2410A AXIS 241SA by host name which is always the same regardless of the IP address Services Enable ARP Ping setting of IP Address The IP address can be set using the ARP Ping method which associates the unit s MAC address with an IP address Check this box to enable the service Leave disabled to prevent unintentional resetting of the IP address 49 50 AXIS 241QA AXIS 241SA System options

DHCP Dynamic Host Configuration Protocol DHCP is a protocol that lets network administrators automate and centrally manage the assignment of Internet Protocol IP addresses to network devices in a network DHCP uses the concept of a lease or amount of time that a given IP address will be valid for a computer The lease time can vary depending on how long a user is likely to require the network connection at a particular location DHCP also supports static addresses for e g computers running web servers which need a permanent IP address DNS Domain Name System DNS is used to locate and translate Internet domain names into IP Internet Protocol addresses A domain name is a meaningful and easy to remember name for an Internet address For example the domain name www example com is much easier to remember than 192 0 34 166 The translation tables for domain names are contained in Domain name servers Domain server Domains can also be used by organizations that wish to centralize the management of their Windows computers Each user within a domain has an account that usually allows them to log in to and use any computer in the domain although restrictions may also apply The domain server is the server that authenticates the users on the network 74 AXIS 241QA AXIS 241SA Glossary Dome network camera A remotely controllable camera mounted in a special housing characterized by the dome shaped glass or plastic cove
