Computing center of the Institute for High Energy Physics in Protvino provides computing and storageresources for various HEP experiments (Atlas, CMS, Alice, LHCb) and currently operates more than150 working nodes with around 3000 cores and provides near 2.5 PB of disk space. All theseresources are connected through two 10 GB/s links to LHCONE and other research networks. IHEPcomputing center has IPv4 address space limited to one C-sized network and all computing nodesworking behind the NAT that has some drawbacks for production use. To optimize routing, switchingand to get higher network throughput for data transfer the IPv6 dual-stack was deployed on thecomputing farm. This work shows the full cycle of the real IPv6 dual-stack deployment from zero toproduction.
