[Dnsmasq-discuss] What is memory usage per cached dns address

[Urgen Sherpa]

Hello :)
Any idea on memory usage per cached dns address ? Lets say if i have
500,000 cache size(and if cache is full) how much memory is expected to be
used on linux server with spare 160G memory?

Currently when cachesize is set to 50, the ps aux RSS is 2500kB with below
logs

Jul 25 17:41:54 servlp6 dnsmasq[15701]: cache size 50, 52/358 cache
insertions re-used unexpired cache entries.

Jul 25 17:41:54 servlp6 dnsmasq[15701]: queries for authoritative zones 0

Jul 25 17:41:54 servlp6 dnsmasq[15701]: server 10.0.3.2#53: queries sent
687, retried or failed 144


root at servlp6:~# ps aux | grep dnsmasq

*dnsmasq*  15701  0.0  0.0  52864  2504 ?        S    16:28   0:00
