System Overview

Hostname: network.england
IP Address: 192.168.0.197
Primary Role: Core Network Services (DNS, DHCP, and Virtual Switching)
Filesystem: Btrfs (Subvolume Optimized)

Core Infrastructure Services

This node serves as the authority for the internal network's identity and addressing.

Service Group	Systemd Unit	Description
DNS (Primary)	`named.service`	BIND9 Domain Name Server handling internal name resolution.
DHCPv4	`kea-dhcp4-server.service`	Kea IPv4 DHCP daemon for dynamic address assignment.
DHCPv6	`kea-dhcp6-server.service`	Kea IPv6 DHCP daemon.
DHCP Management	`kea-ctrl-agent.service`	Control agent for managing Kea DHCP services.
DDNS	`kea-dhcp-ddns-server.service`	Handles dynamic DNS updates between Kea and BIND.

Network Virtualization and Discovery

Open vSwitch: ovs-vswitchd.service and ovsdb-server.service manage software-defined networking and bridging within the host.
Samba: smbd.service and nmbd.service provide NetBIOS name resolution and SMB/CIFS support.
Avahi: avahi-daemon.service provides mDNS/DNS-SD for ZeroConf networking.

Automation and Maintenance

Infrastructure Wake: (22:50) wake_db_server. Triggers a Wake-on-LAN event for the database server.
Consolidated Maintenance: (08:05) morning_maintenance.sh. Handles ping checks and package audits.
