I thought 4353 was F5 in ASCII. But I just looked it up to confirm, and that's not actually the case, unless they are secretly +5.

Tim,
Thank you for playing!! You have to know some of F5's product history to answer the question.
Before there was BIG-IP DNS, there was BIG-IP GTM. Before there was BIG-IP GTM, it was called 3DNS in 4.x. This was the birth of what became the DNS module. The port is a holdover from that legacy.
If you break the port down it answers what process it serves!
4-3-DNS and the port for DNS is 53. Mash it together and you get:
4-3-53 or port 4353.
And now you know!
