sorry I don't get your point, According to you, if I get stopped for speeding I just tell them it's not law.
In the absence of signeage which is normal in the UK but never in Ireland, it varies so much in Ireland if you miss a sign you cannot tell the speed by the type of road. UK uses deristriction sign (black on white no numbers) Ireland does not use this

Where did I say that?

That's just not true. Irish legislation explicitly deals with the default limits by road type (Ordinary, Built-up and Regional & Local) with allowance then for 'special' limits as may be applied locally. In the absence of signage indicating otherwise, the default limit applies. There has been a move to increase the numbers of signs around the country, but by no means are there signs on every single road, nor is there a requirement under law for same.

We just replaced most of those with 100km/h sings on the conversion to km/h for clarity. There are national roads with limits other than (and in cases higher than) 100km/h.

It's more common than you think. Many secondary roads will have a 80km/h limit as any lower would mean any new development is effectively prohibited under the local development plan (much more onerous conditions to get a new entrance in a 50km/h zone). It was a running joke for many years around my home place that a section of the national primary route approaching a bend with hard shoulders had a 60km/h limit while a narrow secondary side-road turning off it had an 80km/h limit. There are plenty of other similar examples dotted across the country.
