using my ESP-12E as little Webserver, I decided to use static IP instead of DHCP.
Is it possible to give the esp a definedhostname?
Actually now, I do not see any hostname on scanning with netscan

Edit: I have found that there is a possibility with

Code: Select allconst char* host = "myESP";
mdns.begin(host, WiFi.localIP()

using this, I see my Webserver with "myESP.local"
But scanning with netscan, there still is no hostname to see

DNS and mDNS are two different things.

and b)
the traditional DNS knows two modes for populating tables: dynamic by dhcp or static via entry by admin.
the third method only exists with M$ Windows DNS and clients: automatically add client info to DNS.

usually your WLAN router should give you a way to configure a fixed dhcp entry (via mac) for your esp8266 that most likely will also take a "hostname"

after certain time, I see after scanning with netscan the hostname I assumed with mdns.begin(host,...)
But in the Router-table there is only an entry with ESP-AABBCC (last part of MAC-address)
Additional I changed tis entry in the table to the wanted hostname.
Then nslookup was fine
