RFC 2182 details the operation and functionality of secondary DNS servers. Which defines/influences how resolvers behave with multiple DNS servers.

When you specify more than one DNS server for network clients, the order in which these servers are used is not random. The following sequence is observed:

Primary DNS Server: Clients will first attempt to use the primary DNS server specified in their network settings. This server is often considered the default.

Secondary DNS Server: If the primary DNS server is unavailable or unable to resolve a query, clients will then attempt to use the secondary DNS server. This server acts as a backup.

So in OPs case his Pihole will always be used if it’s available, and only when it’s not will the secondary be used.

This is great, but let’s be honest it should be Scotland wide. Where I live this is ridiculously common, they get half the car or more on the pavement, stick on their hazard lights and seem to think that’s OK.

One more thing, the fine isn’t high enough in my opinion. There will still be people that’ll carry on parking like this because they justify it somehow. Looking at you Aberdeen Range Rover mob.

I wonder what Infosys promised or paid the congressman.

My wife and merged CD and DVD collections years ago and all our photo albums and documents (in binders) are all in the office, so I guess technically we have access to each others files… does this count?

Well, jokes on you because Range Rover do not refer to the middle picture as a “gear stick”. Probably because there is nothing stick like about it.

You’re lucky, I’m on 25/2Mbps and I pay £32 per month for the privilege.
