ip-address

问题 I have written some C# code that I am using to run an file "snmpwalker.exe" that is returning details about so cisco switches when I pass in the correct community string ip address and vlan information with an OID. I have been able to get enough information to be able to map the MAC addresses to the switch's ports but I want to also find out the ip addresses. Does anyone know what the OID for snmp would be to get back a list with mac addresses and ip addresses on a cisco switch? I haven't

问题 I am trying to find the IP address using HTML coding but I cannot. Is it possible to find the IP address in HTML without using JavaScript or PHP? ping -a ip-adress It displays ping only 回答1: PHP is required - with HTML only its not possible. 回答2: If Apache is set to resolve IP addresses, then you can use <!--#echo var="REMOTE_HOST" --> . However, it is unlikely that your host has that option enabled, because it makes requests take longer. 回答3: You're right, it is not possible in pure HTML

问题 I have an IP with subnetmask and want to create a table in which every row is an IP. Kind of like this: IP | MAC | Alive 192.168.1.1 | ... | yes 192.168.1.2 | ... | no 192.168.1.3 | ... | yes ... For a range with subnet /24, this is easy because I can generate a for loop from 0 to 254 but I'm having trouble with generating the table with a /21 subnet. Is there a way to find in perl what the minimum host, the maximum host and everything in between is? I have checked the Net::IP and the NetAddr

问题 I have created a WCF Service which return JSON data. here is my code: namespace AppServices { [ServiceContract] public interface Service1 { [OperationContract] [WebInvoke(Method = "GET", UriTemplate = "/GetCities", BodyStyle = WebMessageBodyStyle.WrappedRequest, RequestFormat = WebMessageFormat.Json, ResponseFormat = WebMessageFormat.Json)] List<City> GetCityCode(); } [DataContract] public class City { [DataMember] public string CityId { get; set; } [DataMember] public string CityName { get;

问题 How do I calculate the number of hosts in a netmask using TSQL, WITHOUT using a table. For example : IP Number of Host 255.255.255.252 = 4 255.255.254.0 = 512 回答1: Here is the SQLFiddel Demo Below is the sample Query : select (256-T.I1)*(256-T.I2)*(256-T.I3)*(256-T.I4) from ( select dbo.fnParseString(-1, '.', IP) 'I1', dbo.fnParseString(-2, '.', IP) 'I2', dbo.fnParseString(-3, '.', IP) 'I3', dbo.fnParseString(-4, '.', IP) 'I4' from (select '255.255.255.252' as IP union select '255.255.254.0')

问题 How can you calculate the geographic distance (e.g. 500 miles) between 2 IP addresses? Is there some API that lets you look this up? 回答1: you can check this questtion distance between 2 ip address 回答2: This might be the closest you're gonna get: Who provides a WHOIS API? as @carl norum said not all IP addresses resolve to a physical location due to ISP and DNS server locations and other fun routing magic. But if you do get the client's ISP it's up to that ISP to release the physical address

问题 An upvoted SO answer claims: [SSL] breaks name based virtual hosting. With SSL, it's one site - one IP address. Is that true? Does shared hosting that offers SSL certificates lease whole IP ranges? 回答1: With SSL, the server is always authenticated before application data is sent. The "Host" header of the HTTP request is application data. So, in general, you can't use HTTPS with virtual hosting. However, if one party controls all of the sites that are hosted virtually, a single certificate can

问题 I have setup virtual hosts now when I type localhost it does not work I figured that now I'll have to make a virtual host for local host it self and it worked but now when I type my external ip it does not work it says 403 forbidden so how do i fix this do I have to make a virtual host for my external ip and will it work for everyone or just my computer for example if I give to a friend and he typed my external ip will it work? 回答1: When you create Virtual Hosts, Apache ignored the host

问题 Here's what I need to do, any ideas would be helpful. I need to be able to change the Local IP address of a computer programmatically as a limited user in XP. Without giving Admin information to the users. I've played with runas, sanur, and autoit, but all either require giving up the Administrator password or is not extremely reliable. Again, any ideas would be great. 回答1: You should probably create a service that has administrative rights and allow limited users to request an IP change from
