The best certification for networking is CCNA offered by CISCO.To know about other certifications and eligibility and pre-requisites, please check http://www.cisco.com/web/learning/le3/learning_career_certifications_and_learning_paths_home.html
There is a huge scope for networking with jobs ranging from network administrator earning around 3-4 lakhs per annum to developers earning at 10 lakhs per annum.
It will also be an added advantage if at a later point in time, you go for MBA in IT.
