Wireshark · Wireshark-dev: [Wireshark-dev] Determine address type of string

[Jo <wireshark@xxxxxxxxxxx>]

Hello,

I am writing a custom dissector as a plugin. There I need to determine
the address type of a string in a TLV. It can be either an IPv4
address, IPv6 address or a FQDN.

What is the best way to parse this string into the Wireshark data types?

My idea was to check which delimieters occur ("." -> IPv4, ":" ->
IPv6) iand if there dots, to check whether the parts between the dots
are numerical.

Bye,
Jo
