on-premises, cloud, or hybrid environments.\nKey Responsibilities\nConduct a comprehensive assessment of all servers, applications, databases, and network devices currently using public IP addresses.\nDevelop a detailed IP migration plan covering timelines, phased execution, backup strategies, and service rollback procedures when required.\nPerform application and service dependency analysis to identify and mitigate the impact of IP address migration on interconnected systems.\nDesign and allocate new private IP address ranges, ensuring full compatibility with the existing network architecture and infrastructure standards.\nExecute the migration from public to private IP addresses in a secure and controlled manner, while maintaining continuous operation of business-critical applications and services.\nCoordinate with security, systems, application, and operations teams to align firewall rules, routing, NAT, DNS, and access controls with the new private addressing model.\nPerform post-migration validation and testing to confirm service availability, performance, and network stability.\nPrepare and maintain comprehensive documentation for all migration phases, including implemented changes, encountered issues, root causes, and applied solutions.\nAssess and analyze all DNS records to identify unused, obsolete, or outdated entries.\nClassify DNS records based on criticality, activity level, and operational validity.\nRemove or update invalid, obsolete, or unnecessary DNS entries in accordance with approved change procedures.\nEnsure that DNS cleanup activities do not impact applications, services, or end users.\nEstablish periodic review procedures to maintain the accuracy and health of DNS records on an ongoing basis.\nDocument all DNS review, cleanup activities, and applied changes for audit, compliance, and operational reference.\nRequirements\nStrong expertise in enterprise network design, IP addressing (IPv4/IPv6), subnetting, and routing protocols.\nHands-on experience with IP address migration projects in large-scale environments (on-prem, cloud, or hybrid).\nSolid knowledge of firewalls, load balancers, DNS, NAT, VPNs, and network security controls.\nExperience working with high-availability and mission-critical environments, ensuring zero or minimal downtime.\nAbility to analyze complex application-to-network dependencies.\nFamiliarity with change management, rollback planning, and disaster recovery practices.\nBachelor’s degree in Computer Science, Information
