Regarding Sewig address on my Nano Ledger, there are only two real type of addresses: bitcoin legacy and Sewig.
Actually there are more types of 'addresses' than legacy and se
gwi
t.
P2PKH (starting with 1..), P2SH (starting with 3.. (multisignature)), P2WSH nested in P2SH (nested
segwit, starting with 3..) and bech32 (
'native' segwit; startin with bc1..).
The nano s supports P2SH/P2WSH. Thats definetely better than P2PKH addresses but not as efficient as bech32.
based on criteria of segregated witness (segwit) adoption, we can separate them to two types: legacy and segwit
P2SH is considered as legacy address and P2SH-wrapped segwit as segwit address
P2SH-wrapped segwit is backwards compatible with the legacy P2SH address format
while native segwit (bech32) is non-backwards compatible format
