New blog post "My Own DNS Server At Home - Part 1: IPv4" wherein I install and configure a basic BIND DNS server for my network at home. Part 2 will cover IPv6. It's quite hardcore. So if it feels a bit overwhelming, just read it as a nice story and not as a HOWTO. DNS with BIND is a bit demanding, but I find it fascinating!

My Own DNS Server At Home - Part 1: IPv4

ā€œIt’s always DNSā€ is a famous meme among network people. Name resolution is technically quite simple. It’s ā€œjustā€ translating a hostname like jan.wildeboer.net to an IP address. What could possibly go wrong? I am a radical optimist and detail-obsessed knowledge collector, so I decided to find out. As part of my goal to make my home network a little island of Digital Sovereignty, meaning that everything at home should JustWorkā„¢, even with no working internet connection, a DNS server is needed.

@jwildeboer I wish I could get #IPv6 but my #ISP is so incompetentband unwilling to provide details (despite being obligated to do so by law), but given they have absurdly high latency for uplink and downlink (despite being DOCSIS) I am convinced they have some serious peering issues...
@kkarhan @jwildeboer What ISP (ASN)?
@UnderEu @jwildeboer Internet Service Provider & their respectable Autonomous System aka. Network...
@kkarhan @jwildeboer I am asking what ISP (ASN) you're talking about
@kkarhan @jwildeboer So…??? Who is it?

@UnderEu @jwildeboer which one do you guess?

Pritip: they were allowed to buy up almost all cable networks in Germany...
