Abstract :
Allocation of IP (Internet Protocol) is needed in a computer network. The easiest
allocation is to use IPv4, because IPv4 uses a 32-bit format. However, the use of IPv4 has
not been able to accommodate the current IP addressing needs. To meet the needs of the
IP address, IPv6 is needed because IPv6 uses a larger number of bits, 128-bit. Between
devices that use IPv4 and IPv6 cannot be deleted immediately. Therefore the translation
method is used. This research will analyze network performance where the translation
method which is NAT-PT (Network Address Translation - Protocol Translation) uses OSPF
(Open Short Path Firts) routing protocol. This study uses network performance parameters
namely throughput, delay, and packet loss. Based on the results of the study, the average
throughput in file sharing was 6.243 Mbps and in video streaming was 0.279 Mbps. While
the average delay in file sharing is 1,033 ms and in video streaming is 2,382 ms. Then the
average packet loss of video streaming is 0.0000225%. The advantage of NAT-PT
configuration is that it can connect IPv4 and IPV6 addresses.
