DNS Via TCP
Posted: Sun Dec 22, 2019 10:17 am
It seems the standard UPD DNS client is becoming more and more unreliable in the field over the years(?) no matter the Internet access type, so I wondered whether it would be sensible to write/use a TCP version. Does anyone have any thoughts on either the UDP unreliability or the idea of switching the NB client code over to TCP (do DNS servers typically accept both packet types)?
