How a primary/secondary virtual IP address works in different subnets? Case of a mirror cluster with 2 Windows or Linux servers This is the simplest use case for remote sites. When two servers are in remote sites, the previous virtual IP address algorithms are working if they are connected in the same subnet through an extended LAN/VLAN. Thus, clients are reconnected to server 2 running the application which has been restarted on this server by the SafeKit clustering mechanisms. If there is a failure of server 1 and a failover on server 2, SafeKit automatically sends gratuitous ARP to reroute clients ARP caches with the Ethernet address mac2 of server 2.

HOW TO CREATE A APPLICATION THAT SHARES THE IP MAC

If server 1 is the primary server, then the virtual IP address is associated to the Ethernet MAC address of server 1 in the clients ARP caches: mac1 in the figure. Note that with SafeKit, several virtual IP addresses can be set in the cluster on the same Ethernet card or on different Ethernet cards. The virtual IP address is a third IP address coming in addition to the two physical IP addresses of server 1 and server 2. When both servers of the cluster are in the same subnet, the virtual IP address is set on the Ethernet card of the primary server (through IP aliasing). In a mirror cluster, a primary/secondary virtual IP address is required to reroute clients in case of failover. How a primary/secondary virtual IP address works in the same subnet?

Issue Resolution - It can often be more difficult to resolve an issue when sending from Shared IPs. Mailing frequency - There is no minimum mailing frequency needed to qualify for a shared IP, unlike with Dedicated IPs.Ĭost - There is never an additional charge to send from a Shared IP.īad roommates - If the folks you’re sharing your IP with engage in poor sending practices, your email campaigns could be adversely affected.Ĭontrol - You have much less control over your sender reputation. Good roommates - If the folks you’re sharing your IP with follow best sending practices, you would benefit. Some Internet Service Providers (ISPs) throttle IP addresses with no volume history, so you will have to build a reputation over the first few weeks (Marketo can help guide you).Ĭost - There is usually an additional charge to send from a Dedicated IP with any provider. IP warm-up process - Reputation is is built over time. Volume changes - Spikes in volume can negatively affect your reputation and need to be managed. Issue resolution - It’s easier to research, understand, and resolve delivery issues. Monitoring - Monitoring your deliverability reporting enables you to respond quickly to changes in your delivery metrics. Reputation - You wholly own your reputation and deliverability. Which is better - Shared or Dedicated?Īs usual, there are pros and cons to both options. What is a Dedicated IP address?Ī user-specific IP address that only one sender sends from.

This refers to when multiple senders utilize the same IP addresses to launch email campaigns. Shared and Dedicated IP Addresses What is an IP address?Ī numerical label signifying the address of a computer that is connected to the internet.
