Network Services

Network services are all protocols and applications that are related to routing & switching. For example, we have NAT (Network Address Translation) which we use to translate private IP addresses to public IP addresses. There are also gateway redundancy protocols like HSRP, VRRP and GLBP that ensure that our hosts always have a resolvable IP address that they use as a default gateway. DHCP is used to automatically assign IP addresses to routers and/or hosts. In this category, you will find all lessons that are related to these network services and more.
