IP Multipathing (IPMP) in Sun Solaris enables the load balancing capabilities and resilience for Network connections with multple Network Interface Cards (NIC). I discussed here about providing resilience for network connections with multiple NICs on the system. Now, we take it to the next step and make the network connections not only resilient but also

In SPARC Servers running Sun Solaris, you can see multiple Network Interface Cards (NICs) or interfaces are all sharing a single MAC-Address than having a unique Factory-default MAC-Address assigned to it. This is because by default, a System-Wide MAC-Address is assigned to all the NICs and hence a ifconfig -a output will show only one

IP Multipathing (IPMP) in Sun Solaris enables the load balancing capabilities and resilience for Network connections with multple Network Interface Cards (NIC). IPMP is mostly used to provide resilience with network connections wherein a Sun Solaris Server with multiple NICs can be configured such that if the primary NIC fails it automatically failover to the

The Default Gateway or the Default Router is the IP address (IPv4) to which all the traffic to any target destination(s) which does not have a route in the Routing Table of the server will be forwarded. This Default Gateway is maintained in the file /etc/defaultrouter [IPv4 only]

Domain Name Service (DNS) is a system which translates the meaningful Hostnames and Domain Names into valid IP Addresses. A DNS Client or a Resolver is a host or a network device which queries the DNS servers for various resource records like the IP Address for a host like a Mail Server.

Solaris Operating Environment by default is configured to both accept and send the ICMP Redirect messages. According to RFCs, only a router or a gateway device should send an ICMP Redirect message and any other hosts should only be able to receive the ICMP Redirects. If the Solaris server is not acting as a Router

Adding or editing the IP address on a Solaris 10 server is different from the previous versions of the OS (Solaris 9, Solaris 8 etc). In the previous versions of the Solaris Operating System, you need to edit the /etc/hosts file and add/edit the entry for the IP address and the hostname.
