Salah satu faktor yang menyebabkan layanan BaliFiber lambat ada di sisi respon DNS. Pada beberapa kasus ukuran query DNS Balifiber bisa sampai 3x lipat dari DNS lain seperti OpenDNS dan Cloudflare.

Bisa dibilang kualitas DNS Balifiber tidak bagus untuk digunakan sehari-hari, yang ada malah memperlambat proses loading website. Salah satu kemungkinan masalah DNS ini adalah ketika anda mendownload ataupun tes speedtest dapat kecepatan penuh, tetapi sewaktu browsing terasa lambat.

Buat apa 100 Mbps kalo buka google.com aja lambat?

Beberapa contoh

agar output dari dig DNS Balifiber dengan Cloudflare DNS Resolver, bisa dicurangi dengan dig google.com txt +noauthority +noadditional

tetapi tetap saja ukuran data yang diterima tetap besar, perintah diatas hanya menghilangkan bagian yang kurang perlu.

Solusi

1. Dari sisi Balifiber

– pindah web server ke server yang berbeda, gunakan 1 server 1 services
– percepat/perkecil respon dengan hanya menampilkan query yang diminta
– cache dns

2. Dari sisi pengguna/customer
Cara diatas hanya bisa dilakukan oleh pihak Balifiber dan belum tentu dilakukan. Solusinya adalah menggunakan DNS pihak ketiga, seperti

CloudFlare DNS
1.1.1.1
1.0.0.1

Google DNS
8.8.8.8
8.8.4.4

bisa juga digabungkan
dns 1 : 1.1.1.1
dns 2 : 8.8.8.8
setting dns router balifiber

selain kedua cara diatas bisa juga dengan Unbound atau DNSCrypt untuk caching query DNS anda.

DNS Server Balifiber

Bagi anda yang mau tau software apa dibalik DNS Balifiber, lihat dengan perintah

> nslookup -q=txt -class=CHAOS version.bind 103.94.168.168
Server:		103.94.168.168
Address:	103.94.168.168#53
 
version.bind	text = "9.10.3-P4-Ubuntu"

Dari informasi diatas bisa kita ketahuin DNS Balifiber menggunakan Bind9 di Ubuntu
