Abstract

Every computer needs and must have an IP Address to connect with other computer network users, the IP Address will be automatically distributed to network users using the Router as a DHCP Server. In addition to DHCP, the Router has a DHCP Accounting service that can improve network security with AAA and RADIUS Server features that can be implemented with Freeradius. DHCP Accounting has accounting capabilities for secure START and STOP message transmission, but the flash memory capacity on the C2691 router is around 32 MB, making the DHCP Accounting service not run optimally if it has many users. Using MySQL as a database can be a solution to this problem. When using the DHCP Accounting feature, data from DHCP Accounting will be sent and centralized on Freeradius. Accounting data centralized on Freeradius will be stored using a MySQL database so that the available storage space will be much larger and can accommodate more data from DHCP Accounting, as well as monitoring the network so as to improve network security for users.

Abstract

DNS-based ad blocking is used to increase website access efficiency by reducing unnecessary elements. This research analyzes the effect of using AdGuard Home in the MikroTik container on response time, delay and data transfer  when accessing website. This research used an experimental method, with 30 tests before and after the implementation of AdGuard Home. Google DevTools was used to measure response time and data transfer , while Wireshark was used to measure delay. The results show that response time decreased by 36.38% from 78.46 ms to 49.91 ms, and data transfer  decreased by 42.25% from 7.1 MB to 4.1 MB, indicating an increase in network efficiency. However, the delay increased by 12.3% from 256.9 ms to 288.5 ms, due to additional latency in the DNS filtering process. Thus, this research proves that AdGuard Home in the MikroTik container can increase website access efficiency by speeding up response time and reducing data transfer , but increasing delay. Further optimization is needed to reduce the impact of delays to maintain an optimal user experience.
