IP or DNS in connection string - not critical
Hi,
My provider has provided me with an IP address and a DNS name to the SQL
server I use. Whilst both obviously work does anyone know if there is any
performance increase in using the IP address to avoid DN resolution?
I imagine any performance will be negligible.

If the DNS servers are under a DDoS attack you will notice it stop
working while the IP address will work so long as it doesn't change.
This means they both have advantages. DNS for changing the IP without
recoding & IP address for less susceptibility to DDoS attacks.

That is unless there are other things which I didn't think about.
