IRC clients are computer programs that users can install on their system or web based applications running either locally in the browser or on 3rd party server.
These clients communicate with chat servers to transfer messages to other clients.
DALnet ircd modifications were made by Alexei "Lefler" Kosut.
DALnet was thus based on the undernet ircd server, although the DALnet pioneers were EFnet abandoners.
The first part he implemented was the chat part, which he did with borrowed parts written by his friends Jyrki Kuoppala and Jukka Pihl.
The first IRC network was running on a single server named fi.
According to James Ng the initial DALnet people were "ops in #Star Trek sick from the constant splits/lags/takeovers/etc".
DALnet quickly offered global Wall Ops (IRCop messages that can be seen by users who are w (/mode Nick Name w)), longer nicknames, Q: Lined nicknames (nicknames that cannot be used i.e.

The "undernetters" wanted to take ircd further in an attempt to make it less bandwidth consumptive and to try to sort out the channel chaos (netsplits and takeovers) that EFnet started to suffer from.
